There are many lawyers who claim aviation accident experience but who have little or none but may be successful in other fields.

Here are a few important questions to ask.

  1. How many aviation accident cases have you handled?
  2. How many aviation accident cases have you tried to verdict?
  3. What were the verdicts in those cases?
  4. Are you a pilot?
  5. How long have you been a pilot?
  6. Have you personally flown the aircraft involved in this accident?
  7. Did you personally investigate this accident before I called you?
  8. What do you think happened?
  9. Do you personally know the management of the aircraft manufacturer?
  10. Do you personally know the management of the engine manufacturer?
  11. Have you settled cases with the insurers for the aircraft or engine?

Two pilots are dead in the fiery crash of a Beech E-90 King Air. The aircraft was equipped with four bladed propellers. While giving a quieter ride, these four-bladed propellers are like barn doors in the event of engine failure.

The investigation is just beginning but there is just no reason for an aircraft like this to crash absent a loss of power on one side.

The original aircraft was equipped with 3 bladed propellers and VMCA, minimum control airspeed with the critical engine wind-milling was computed with the propeller not feathered. When equipped with four-bladed propellers, the VMCA goes through the roof, some 30 knots higher and landing speeds are below VMCA. Absent immediate feathering of the propeller on the affected engine, the airplane will slow down and stall. On takeoff the airplane will roll towards the inoperative engine until upside down.

I have no doubt these pilots were skilled and experienced but taken by surprise recovery from an engine failure is no easy task.

Typical reasons for engine loss of power are PY air leak, bleed valve failure or less likely a catastrophic failure of either the power section or gas generator. In some modes of failure there is no annunciation of that failure to the pilots.

The Wolk Law Firm has handled a dozen King Air crashes due to loss of power.

May their memories be a blessing.

Witnesses describe the takeoff as a sudden pitch up, the airplane stalled and then crashed to the ground killing young flight instructor Viktoria Ljungman and injuring her student.

This has happened time after time in single engine Cessna’s when either the pilot’s or front passenger seat slides suddenly rearward while the pilot is holding onto the flight controls.

The grasping reflex causes the person in the pilot’s seat to hang on for dear life as the nose of the airplane pitches up too steeply to recover before stalling.

The surprise makes it impossible for even a flight instructor to wrest the controls away from the student  in time to save themselves.

The Wolk Law Firm obtained the largest aviation verdict of all time against Cessna for just such an accident. We are litigating another such crash that occurred in West Virginia under similar circumstances. In that accident the flight instructor’s seat slipped rearward on takeoff and the student was seriously injured though the flight instructor perished.

The Wolk Law Firm provided Cessna with a fix for this problem back in 1984 to no avail and again in the 1990’s again to no avail. There are still thousands of Cessna single engine airplanes out there with legacy seats that run the risk of similar accidents. The problem is the steel pins used to restrain the seats ride on aluminum rails which rapidly become worn such that the seat can slip. It happens on takeoff because the seat bends and ratchets out of the seat attachment hole as it is a flimsy design.

So long as Cessna makes no necessary changes these accidents will continue to happen and young pilots and student pilots will be killed and injured needlessly.

May the memory of  Viktoria Ljungman be a blessing to her family and hopefully her student will fully recover from his injuries.

In Memoriam F.T. Bradshaw

In everyone’s life there are a handful of people who make a difference. Tom Bradshaw was just such a person for me. He was the President of Halton Hall, a first-class insurance agency specializing in aviation insurance risks. What no one else could get underwritten, Tom by his very stature in the industry could get done.

His loyalty is legendary. If you treated him, his company and more important his insurance industry base with dignity, fairness and honesty there was no better representative.

In this world there are few people who make their mark so indelibly that others are amazed at how much they have achieved with such dignity.

F.T. Bradshaw, Tom, will be sorely missed.

May his memory be a blessing to his family, his employees and colleagues.

Old airplanes by definition have been around for a long time. There is something charming about flying in a vintage airplane put to use in romantic settings.

There’s a problem though. Old airplanes break a lot! No matter how much maintenance, how many modifications, upgrades and replaced parts there have been old airplanes just fail more frequently than new ones do and new ones fail a lot.

The problem with old airplanes is that seals get dry, gaskets rot, rubber parts harden and crack, composite parts wear out and even metal gets fatigue from expansion and contraction due to temperature changes and pressure changes and simply from moving and working the metal into brittleness.

Often, modifications are made through STC’s, a process that allows changes to an airplane with much less scrutiny than the original certification process which is bad enough, often allowing the manufacturers themselves, through the honor system, to essentially certify their own aircraft.

The Cessna Citation 501 has been around since the 1970’s and pressurization problems were reported in this aircraft.

Oxygen masks should have been sufficient for the crew to have landed without incident but for some reason the pilot chose to fly in a circuitous route before crashing into the sea. Oxygen deprivation is serious business and the outcomes are usually not good. Pressurization in light jets is accomplished by taking air off the engines and sending it into the front of the cabin and controlling its exit through outflow valves in the rear. The failure of either the entry controls or exit controls means pressurization failure which can mean loss of useful consciousness in as little as 20 seconds. Quick donning of the oxygen masks for the crew and a sufficient supply of oxygen for everyone is critical.


The De Havilland Otter is the workhorse airplane for odd places. It carries a lot, like 9 people or more and loads of cargo. In fact, it has so many STC’s its hard to count the many ways that it has been modified to carry more revenue producing people and cargo. Its engine was a turbine so the aircraft’s

old reciprocating engine was replaced with a much newer turboprop which would allow it to carry even more people and freight. The airplane however was sixty years old or more. Lots of them have been modified with floats or skis so they can be landed on water, ice and snow.  They have been used safely for decades. But they also crash a  lot because of the harsh environments in which they are used.

The Wolk Law Firm represents the families of a tragic fatal accident in Homer Alaska where the float of a De Havilland Beaver ( a smaller version of the Otter) became detached during takeoff causing the airplane to cartwheel and sink. The float was almost new, the attaching wires were almost new but because of poor and inadequate design the old airplane crashed. As an Airplane Transport Pilot Single and Multi-Engine Sea, I can say that taking off and landing on water can be challenging especially when things go wrong. While most think water is soft, it has little compressibility and can be as hard as concrete so a walk-away from a seaplane crash is no guarantee. Moreover, seaplanes operate in harsh and typically salty environments which wreaks havoc on metal parts. Salt can corrode metal spars and other aluminum parts so they are understrength. One multi-engine seaplane crashed in Florida killing all aboard because of corrosion of its main wing spar and a wing fell off.

The NTSB recovered much of the wreckage of the Otter and did find a failed stabilizer trim part that can explain the loss of control. The horizontal stabilizer is used to provide pitch stability and to trim pitch forces by moving its leading edge up or down. Disconnection can result in loss of pitch control which has happened before in other aircraft including an Alaska Airlines MD-80 that crashed into the Pacific years ago.

Old airplanes are difficult to maintain and fail catastrophically. The airlines learned this and renew their fleets more frequently now.

There is no coincidence that both were very old and old airplanes just like people don’t live forever.

There is no doubt that inadequate maintenance will have contributed to these accidents and perhaps defective design or manufacture. No airplane accident has one cause.

To the families of those who did not survive, may their memories be a blessing.

A Cirrus SR22 piloted by an experienced and well-respected pilot was on approach to Wings Field, Blue Bell Pennsylvania when it suddenly lost power requiring an emergency landing on a golf course.

Both occupants survived though injured. This crash is important because the pilot survived. He will be able to explain his power loss which prevented him from achieving enough power to even maintain level flight. Plenty of fuel, no expense spared for maintenance but yet another two occupants were nearly killed when the powerplant failed.

There have been more than 100 losses of power in this model Cirrus. Many have been killed or injured and while the aircraft has a ballistic recovery system, a parachute that can be used to lower the aircraft to the ground safely, many pilots either cannot or are reluctant to pull that handle because it works only about 80% of the time and destroys the airplane.

The solution for Cirrus is to do away with this unreliable powerplant and develop with partners or buy an off-the-shelf turboprop powerplant which has immense reliability compared to the turbo-normalized piston powerplant it used in this model. Later models used an even more unreliable turbo-charged engine. A turboprop engine is a jet engine attached to a propeller and does not suffer the unreliability issues that piston engines do.

That switch would increase the cost of the aircraft which is now expensive at a million dollars each but each accident costs Cirrus millions to defend and compensate so the cost benefit should be obvious.

The impact on the victims and their families is unspeakable and morally there is no choice but to improve the Cirrus and its safety record.

The Wolk Law Firm has litigated many Cirrus loss of power accidents and while the NTSB will no doubt find nothing to explain this power loss, we recommend looking carefully at the turbo, its bearing and controller, the fuel pump and its controller and whether the exhaust system was functioning as it should just prior to the crash. Absent a catastrophic failure of the crankshaft, a broken rod or a hole burnt into a piston, it is likely the more obtuse causes that explain this sudden loss of power.

Cirrus is now explaining away the accident by claiming that the pilot ran out of gas. Well he didn’t. In fact, he stopped in South Carolina for fuel and was only 3 hours into the flight when the engine lost power, it never quit, it just couldn’t maintain flight. That’s how airplane manufacturers work. After spending the better part of a million dollars with them, they become your adversary when the defects they built in cause a crash.

Kudos to the pilot who successfully made an off-airport landing.

Essex County New Jersey Bell 407 Helicopter Crash Is Eerily Similar to Charlottesville Virginia Crash of The Same Model That Killed Two Virginia State Police Troopers.

A Bell 407 piloted by an experienced  charter helicopter pilot crashed at the Essex County New Jersey Airport injuring the pilot.

The craft was seen rotating before the crash and pictures taken at the scene reveal a severed tail rotor driveshaft and fractured rotor blades. The tail rotor in that model counteracts the torque from the rotor blades and without it, the helicopter will rotate and it is a miracle that a safe landing was achieved.

The main rotor blades contacted the tail boom of the helicopter and severed it but that only can happen if a mechanical failure induces the main rotor blades to flap excessively. That happens due to delamination of the composite rotor blades resulting in excessive flapping, a stuck anti-torque-pedal limiter or sudden engine overspeed. All three have resulted in Model 407 accidents.

The Wolk Law Firm is litigating the deaths of two Virginia State Troopers killed when their Model 407 did precisely the same thing as in this latest accident, but it also fell into trees and burned.

Bell is defending the Virginia State Police case claiming that LTE or Loss of Tail Rotor Effectiveness and Vortex Ring State caused the Virginia accident, all of it totally made up. The problem is that both are defects in the design of the helicopter but neither caused that accident or this one.

In the Virginia crash, witnesses saw the helicopter rotating before it settled into the trees and it too had a severed tail rotor driveshaft and fractured main rotor blades.

The Model 407 has a bad accident history with one Band-Aid after another applied by Bell.

Perhaps this pilot who mercifully lived will be able to tell his story because in Virginia Bell relies on the fact that dead men tell no tales. They can’t!

Young Daniel Perelman was by all accounts an aviation enthusiast realizing his dream of becoming a pilot.

He was on his first solo, a landmark event in any young pilot’s life, when he reported engine trouble and crashed suffering life taking injuries. This is a sad day for the Perelman family.

The Cessna 152 he was flying has been around for decades. I trained in its predecessor the Cessna 150.

It has three flaws that no doubt contributed to this crash and the injuries suffered.

The first is that the design of the Cessna fuel tanks does not allow the complete removal of water and other sediments from the fuel. It is possible for a pilot to do a thorough pre-flight, draining the fuel tanks from the small drains at the bottom and never remove all the water because the drains are above the lowest point in the tank.

The second is that the engine is carbureted which means that even if the engine holds together after the hard use a trainer gets, fuel starvation or over enrichment can occur due to the lack of precision of the fuel delivery system. Carburetors work a little like a toilet water fill system. They have a float that shuts the replenishment of fuel when it gets too high in the bowl and allows the fuel to refill the bowl as necessary when the fuel is used. Often the needle valve gets stuck which is the Achilles heel of the system and will shut the engine down by either starving it of fuel or making the mixture so rich that the engine won’t run or loses power.

Carburetors also suffer from carburetor ice which forms inside the carburetor as the fuel expands in the air with which it is mixed. The temperature drops and ice can form if it is humid. This model engine is usually immune from carburetor ice due to the location of the carburetor especially on takeoff but the Cessna 152 does have a carburetor heat handle so it is not impossible.

The third flaw in this aircraft is its complete lack of crashworthiness. It is an unfriendly environment in case of accident. No airbags, no soft energy absorbing materials, inadequate seat belts and harnesses and many switches and knobs that are dangerous in the event of an impact because the fuselage does not attenuate impact it instantly contracts in size and then expands called spring back. The lack of structural rigidity enhances injuries.

Most trainers are fairly Spartan to keep the cost down but while not a perfect solution, selecting a more modern trainer with some built in safety features like fuel injection, crashworthy interior and a ballistic recovery system can lessen the risks that are always inherent in a single piston engine design.

The loss of any young life is an unspeakable tragedy. May this young man’s memory be a blessing.

This win is especially poignant because of the abuse by the defense. The first trial took three months while the defendant deliberately delayed the trial. It filed no less than 8 appeals that were all thrown out.

The first trial ended in a mis-trial because the jury couldn’t stay longer and had served for months while the defense made it a point to waste their time.

The second trial was more of the same but the case went to verdict and the jury entered a 9-million- dollar verdict for Plaintiffs. The defense appealed that too but in a 34-page opinion the Superior Court of Pennsylvania rejected the defense arguments and affirmed the verdict and post-trial decision of the Court.

This decision is significant because it is one of the few trial court verdicts and post-trial decisions after the Pa. Supreme Court overhauled Pennsylvania’s Products Liability Law.

It affirms the ability of the trial judge to make issue by issue choice of law decisions and reaffirms the long-standing law that failure to create a record below makes an appeal non-justiciable as to that issue. The decision also made it clear that failing to adequately argue points on appeal with cogent citation of cases that are in point renders the appellate Court unable to address that argument.

This result is a relief to the Lallo family who have waited 9 years since the death of the mother and father in an airplane crash in Kansas City just moments after a visiting to celebrate the birth of their newest grandchild.

While the case should be over, the option remains for the defendant to ask the Pa. Supreme Court for relief but the strength of the Superior Court’s opinion should deter any reasonable legal mind from pursuing that course which will be unavailing while interest on the verdict mounts daily.

Cynthia wrote the brief and argued the appeal and deserves great credit for a magnificent result.

An airline that maintains its own flight school wants the FAA to reduce the required flight time for its first officers from 1500 to only 700.

It claims that in 700 hours its student pilots have enough experience to serve in a support capacity to a Captain who has more than the required flight time and will not compromise safety.

The 1500-hour requirement for first officers followed a tragic crash of a Colgan Airways turboprop crash in icing conditions on approach to Buffalo N.Y. While the NTSB’s probable cause unfairly blamed the pilots, the new higher flight experience requirement for first officers was designed to bring more skill into the cockpit.

Here’s the problem with the airline’s logic which the FAA will likely go along with. Flight time is not an indicator of experience, it is a number of hours of flight time. Experience is time in the air, time in the type aircraft and years of experiencing all types of weather, lots of emergencies and abnormal conditions in airplanes. That’s why big airlines always had an apprentice program that required a pilot to get years in the cockpit before he became qualified to be a captain or even a first officer.

If the FAA allows this reduction in flight time to be the rule, I predict an airline safety disaster. I had friends who claimed to know it all after just 600 hours. They didn’t but are a risk to themselves and others. The FAA statistics show that most accidents occur when the pilot has between 500 and 1000 hours pilot time. That’s the “I know it all.” period and before a pilot starts to learn that he doesn’t know it all after all.

This proposed reduction of required flight time is a mistake and will make us all less safe.
