Did the Pilots Attempt to Fly Through a Thunderstorm Intentionally? That’s very unlikely. Pilots avoid thunderstorms at all costs, because they know a thunderstorm can destroy any aircraft. Pilots use the aircraft’s on-board weather radar system to make sure they keep a safe distance. During the day, they can see the towering thunderstorms rising up to 50,000 feet and avoid them that way as well.

Did Lightning Destroy the Aircraft? Probably not. Lightning strikes are common. On average, each airplane is the US commercial fleet is stuck by lightning once per year. To protect against strikes, airliners are designed to route the electrical charge along the aircraft’s outer skin from one end of

What does the aviation accident lawyer need to prove in order to win a "design defect" lawsuit against the manufacturer of the aircraft that injured his client?   

It varies from state to state. But it’s never enough simply to prove that the aircraft‘s design caused the accident or injury.  The victim’s lawyer always has to prove more than that.  One way for the aviation lawyer to win the lawsuit under California law is to prove to the jury all of the following things:

  1. That the pilot did not misuse the aircraft, but instead operated it in a way the manufacturer could have anticipated;Zodiac CH 650
  2. That the aircraft’s design presented a real risk of injury, and not just a remote possibility of injury; 
  3. That a different, safer design would have avoided the accident or injury, and
  4. That the safer design was “feasible.”  In other words, a safer design would not have been too expensive, been too difficult, made the aircraft too heavy, significantly detracted from the aircraft’s performance or usefulness, or presented other serious drawbacks.

To support the case, the victim’s lawyer can present to the jury evidence such as the testimony of expert engineers, pilots or eyewitnesses; documents from the manufacturer’s files; pieces of the aircraft wreckage; “mock-ups” of safer, alternative designs; and laboratory test results.  He cannot, however, use any of the conclusions or opinions contained in the National Transportation Safety Board report concerning the accident.  That’s because the NTSB’s opinions are inadmissible in court.

After all the evidence has been presented, the judge explains to the jury exactly what the victim’s lawyer needed to prove in order to win. The explanation is called the "jury instructions."  The judge gets the instructions from standard, pre-published forms that he modifies as needed for the particular case. 

For the victim to win, the jury must agree, after reviewing all the evidence, that his lawyer proved his case by a "preponderance of the evidence."  That means that the evidence, taken together, showed that each element of the victim’s case was “more likely than not” true.  The lawyer need not prove his case “beyond a reasonable doubt.” That standard of proof applies only in criminal cases.  

The General Rule

Mechanics are required by regulation to follow the instructions set forth in the manufacturer’s maintenance manuals when working on an aircraft.  The mechanic is not allowed to deviate from the instructions covering the work he undertakes.  If he does deviate, and someone is injured as a result, the mechanic is liable.

Service Bulletins

Sometimes, a manufacturer learns of a problem with the way its product is performing in the field.

I blogged here on whether it was icing that caused the crash of Flight 3407, or whether the pilot simply pulled back on the yoke when he should have pushed forward.  The NTSB’s animation, using data gathered from the aircraft’s black boxes, makes a strong case for the latter.

The video is 2 minutes 39 seconds long.  Watch the airspeed drop dangerously low by 2:04 and the stick shaker activate at 2:07.  The pilot should have immediately pushed the yoke forward, which would have pointed the nose down and allowed the aircraft to regain airspeed.  Instead, he pulls the yoke back.

Cory Lidle’s wife and Tyler Stanger’s family are suing Cirrus Design, alleging that a problem with the plane’s flight controls caused Lidle and Stanger’s plane to crash into a Manhattan hi-rise.

Miles O’Brien, a former CNN correspondent, calls the lawsuit frivolous, because the NTSB concluded the cause was pilot error.  According to O’Brien, "in our litigious society, the facts don’t matter for much."

O’Brien is missing the fact that the NTSB’s conclusion is marred by a built-in conflict of interest.

The Cirrus is a “new generation” aircraft loaded with safety features. For example, if a pilot flying after dark gets too close to a ridge line, the Cirrus’ on-board Terrain Awareness Warning System generates a voice urging him to “Pull Up! Pull Up!”  The plane’s wings secrete fluid that helps prevent them from icing up in poor weather. The cockpit has airbags, and its seats protect the passengers in a crash by absorbing 26 times the force of gravity.  The Cirrus is the only aircraft of its kind that comes with a rocket propelled parachute that can shoot out of the back of the plane in an emergency. Partly as a result of all its safety features, the Cirrus has become the most popular general aviation aircraft, with sales surpassing long-time industry leaders Cessna, Beechcraft, and Piper.

Critics, however, say that the aircraft has a lousy safety record, with a fatal accident rate significantly higher than the “old style” Cessnas and Beechcrafts. They say that the Cirrus, made mostly of fiberglass rather than the traditional aluminum, is not crashworthy. Not only does the

The National Transportation Safety Board doesn’t have the engineering expertise or financial resources to investigate an accident on its own. So it asks industry representatives for help.  In almost every case, it turns to the manufacturer of the aircraft component that failed or malfunctioned.  In other words, the NSTB asks the entity most likely to have caused the crash for NTSB Investigator Gathers Data at Crash Sitehelp investigating it. The NTSB calls this method of investigation the "party system."

Can we really expect a manufacturer to point out to the NTSB evidence suggesting that it may have been at fault?  Of course not.  Asking industry representatives to help determine the cause of an accident is like asking the fox to help figure out what happened to the chickens.

Victims’ families are not allowed to participate in the NTSB’s accident investigations. Nor are experts hired by the families or by the families’ attorneys. So the investigation is necessarily one-sided, with the NTSB’s final report heavily "influenced" by the very corporations whose products or services are being investigated. The NTSB has recognized the conflict of interest inherent in its "party system" but, unfortunately for victims and their families, continues the practice in just about all of its investigations. 

The Washington Times recently reported that British Airways passengers may proceed with their lawsuit for compensation for lost baggage.  British Airways loses 23 bags per 1,000 passengers carried, a rate more than 60 percent higher than the industry’s average, according to the Air Transport Users Council. 

The Warsaw Convention limits to $9.07 per pound what a passenger can recover against an airline for lost luggage, up to a maximum of  $1500 per bag. The frustrated passengers’ class action lawsuit (pdf) seeks to recover the full value of items lost, even if it exceeds the Warsaw Convention’s monetary limit, because British Airways prematurely auctions personal items that inspectors remove from baggage– such as iPods, digital cameras, computer laptops, and mobile phones– instead of giving the passengers a reasonable chance to reclaim them. The passengers say that the airline auctions off items which have only been ‘missing’ for a few weeks.

British Airways says the suit overreaches. Nonetheless, federal judge Nicholas G. Garaufis has permitted the lawsuit to continue (pdf). The passengers may have found an ally in Judge Garaufis.  But proving willful misconduct — required before the passengers can bust the Warsaw limits — will be difficult.   My prediction: the passengers’ lawsuit, like their baggage, will ultimately be lost. 

Flight Safety Foundation has released a study identifying the most significant risks involved in the helicopter air ambulance industry. The safety study was undertaken in response to the industry’s increasingly poor safety record.

According to the 64 page report (pdf), one of the biggest problems is that it’s not clear who is in charge of overseeing the industry.  State agencies, county agencies, and federal agencies all have a hand in regulating air ambulance operations but there is little coordination between them. Because no one agency is clearly in charge, hazards cannot be appropriately identified or managed, and definitive industry standards cannot be established.  

The report went on to identify 25 other significant risk factors.  Among the problems discussed:

  • Good decisions aren’t being made about whether a patient actually needs air transport.  Unnecessary flights lead to increased crew pressure and fatigue.
  • The industry lacks a real “safety culture.”  That can give rise to environments that reward inappropriate risk-taking behavior.
  • There is not enough money available to upgrade the EMS helicopters with current technology.
     

The report was underwritten by Bell Helicopter.  Though interesting reading, there’s little in the report that those familiar with the air ambulance industry would find surprising.

Right after the crash of Flight 3407 at Buffalo, investigators  focused on the aircraft’s deicing system. The question, as explained by former CNN reporter and pilot Miles O’Brien, was whether ice had accumulated on the plane’s wings faster than the de-icing system could remove it, leading to an aerodynamic “stall,” or loss of lift. 

But as the investigation progressed, it began to look as though, just before the pilot lost control of the aircraft, the nose of the plane pitched up  — not down as usually happens when ice overwhelms an aircraft.  That raised an almost unthinkable possibility:  gross pilot error.  When an aircraft gets
