The NTSB has released its preliminary report of the off-airport landing of Lancair IV-P N9JE at Hilton Head.  The accident killed a jogger but left the plane’s two occupants uninjured. According to the preliminary report, 

Further examination of the airplane revealed that the propeller assembly separated from the crankshaft flange and was missing.

In other words, the crankshaft failed.

One wouldn’t expect a crankshaft to break absent some sort of defect. If that proves to be the case, could the manufacturer of the crankshaft be held liable to the jogger’s family?

The aircraft was built from a kit and was thus "experimental." The engine, however, was not. Rather, according to FAA records, it appears that the engine was an FAA-certified, turbocharged piston engine manufactured by Teledyne Continental Motors, a company that has had its share of lawsuits related to its engines coming apart in flight. 

The General Aviation Revitalization Act, or GARA, protects aircraft engine manufacturers from liability for defective engine parts older than 18 years.

We don’t know how old the engine was in this case.  However, the Lancair builder had reportedly taken the engine from a Piper Malibu.  Piper stopped using the Teledyne Continental TSIO-520 engine in its Malibus due to reliability problems. In 1988, it switched and began installing Avco Lycoming engines instead. Thus, if it turns out that the engine was an original equipment Malibu engine, then it had to be at least 20 years old -- 2 years beyond GARA's age limit.

So is Teledyne Continental Motors off the hook, regardless of whether the jogger's family can prove that the engine was defective? 

No.

There is one important but little-known exception to GARA.  Regardless of the defective part's age, GARA doesn’t protect its manufacturer from lawsuits brought by the families of those killed on the ground.

That's the number one question I've been asked about this accident.  Not "why did the accident happen," but "why didn't the pilot use the parachute?"

As I note here, most Cirrus pilots would say that the parachute should be deployed in the event of engine failure, unless there is a long, paved runway beneath the aircraft such that a safe on-airport landing is assured.  But that doesn't mean that, if there is no airport within range, a pilot who opts to glide to a field rather than pull the chute is negligent.

Pulling the parachute has serious risks.  The aircraft's rate of descent under the parachute is high.  Ground impact forces are severe. Cirrus warns that the decision to deploy the parachute should

Nothing scares helicopter pilots more than wires. Flying into a wire is often fatal. What worries the pilot is that wires are hard to spot. The trick is to look for the towers. Once you see the towers, you can spot the wires strung between them.

But not always.

In January, a California Fish and Game helicopter flew into wires near Auberry, California. Four died in the ensuing crash. Two families have now sued Southern California Edison, alleging that the power company should have marked its wires with orange balls to make them more visible.

The twist to the case is that the helicopter did not strike the 2” thick high tension wires that carry electricity.  Rather, it flew into thinner, harder-to-see “static lines” that were strung above the high tension wires.

From one of the lawsuits:

The transmission lines directly over Willow Creek span 3,000 feet from tower to tower. . . Static lines are normally within several feet of the power transmission lines however on the 3,000 foot span the static lines were constructed and maintained so as to be significantly elevated above the power lines. . . . helicopter pilots flying in and about transmission lines would form the belief that the static lines would be maintained at the approximate same distance above the power lines . . . Because of the size of the static lines, they are nearly invisible until they are within about 285' so that at a nominal speed of 60 knots the pilot has no more than 2.8 seconds to observe the lines and avoid them whereas with colored ball warnings on the lines they are easily seen from a safe distance to allow pilots to identify the lines and to easily avoid the hazard of them.

Here is a photo of marker balls installed on a nearly invisible static line, and the high tension wires that hang below.  (This is not the accident site.)  Note what a difference the balls make.

A Cirrus SR-22, N224GS, crashed yesterday in Washington state.  The pilot was killed.  The passenger was critically injured.  The aircraft departed Concord, California (CCR) in good weather, bound for home.  It crashed in Morton, 60 miles from its destination, which was presumably Renton (RNT).

The accident appears to have been the result of engine failure:

• Witnesses said it was flying "low and silent" just before impact.
• A pilot on frequency says he heard the Cirrus pilot report to Air Traffic Control "saying he was dead stick "no engine" and he didn't think they were going to make the airport."

Facts suggesting that the engine failed because it ran out of gas:

• Fuel exhaustion is the leading cause of engine failure.
• The pilot reported to his wife that he was battling a "stiff headwind." Unexpected headwinds are common to many fuel exhaustion accidents.

Only modifications that carry a Supplemental Type Certificate may be legally installed on an aircraft. The Supplemental Type Certificate guarantees that the FAA has thoroughly tested and reviewed the modification. And it's the Supplemental Type Certificate that insures that the modification is safe and compatible with the particular model aircraft on which it’s being installed. Right?

Maybe not. Owners really shouldn't place too much stock in an STC. Or so says one former NTSB accident investigator. The investigator, now retired, explained to me that most owners might be surprised by how little work the FAA does before issuing an STC. Sure, the STC process is a huge paperwork shuffle for the modification's manufacturer. But it's little more than that. The process seldom entails any real independent engineering cross-check on the FAA's part.

"Give me an example", I asked. "OK,' he said. "Let's talk tip tanks."

A popular modification for many models of Cessna single-engine aircraft are wingtip extensions that

Most general aviation aircraft manufactured today come with "glass cockpits."  Instead of being equipped with mechanical gauges and indicators, they are equipped with computer screens.  The screens integrate and display all sorts of useful flight information.  The information displayed may include satellite weather, synthetic vision, infrared vision, terrain awareness information, traffic

Other countries severely limit compensation that may be awarded in wrongful death lawsuits arising from airline accidents.  For example, many other countries do not allow families to be compensated for loss of a loved one's "care, comfort, or society."  As a result, in almost all situations, the best venue for a family's lawsuit against an airline is the United States.

If the airline passenger's trip included an international stop, then the proper venue for the lawsuit is controlled entirely by international treaties known as the Warsaw and Montreal Conventions.  The Warsaw Convention permits the passenger (or the passenger's family) to sue in the United States, even though the accident happened on foreign soil, if and only if:

1. The passenger's ticket was issued in the United States;
2. The passenger's journey was a round trip that started in the United States or was a one-way trip that ended in the United States; 
3. The airline is incorporated in the United States; or
4. The airline's principal place of business is in the United States.

The Montreal Convention has replaced the Warsaw Convention in most situations. The Montreal Convention adds to the list what has been called a "fifth jurisdiction." Regardless of where the accident occurred, or where the passenger began or ended his trip, the international traveler or his family may sue the foreign airline in the United States if the United States was the passenger's "principal and permanent residence."  For this fifth option to be available, however, the airline must maintain some sort of presence in the United States.
