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 theTana Ball 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:

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 CertificCessna Floatplane(Photo by TailspinT)ate 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.International Flags

If the airline passenger’s trip included an international stop, then the proper venue for any lawsuit against the airline 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 the airline 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.     

The NTSB released its preliminary report on the Pine Mountain Lake crash.  As usual, the preliminary report contains no conclusions concerning the cause of the crash. For that, we’ll have to wait up to 4 years.  The preliminary report does, however, hint that the NTSB’s investigation will focus on whether the pilot pressed on into weather beyond what the regulations allowed.

The full text of the report is here.  Some excerpts:

Instrument night meteorological conditions prevailed at the accident site, and no flight plan had been filed.

Instrument weather conditions are those that require a pilot to fly by reference to his instruments rather than by looking out the window. To fly in instrument conditions, a pilot must be instrument-rated, his plane must be properly equipped, and he must have a clearance from air traffic control.  He is not necessarily required to file a flight plan.  For example, instead of filing a flight plan, the

The runway at Pine Mountain Lake is oriented east-west, and is surrounded by rugged terrain.  In poor weather, pilots are permitted to execute instrument approaches to the airport.  The approach procedures guide pilots as they descend through the clouds to the runway.  The procedures, flown properly, will place the pilot in a position to land straight ahead without having to maneuver.  When the pilot pops out of the clouds after flying the instrument approach to Pine Mountain Lake, his view out of the windshield should be something like this:

The procedure the pilot must follow when approaching from the east is set forth below.  A pilot may descend in the clouds no lower than 770 feet above the runway.  To descend further, the pilot must

The initial investigation was conducted by local law enforcement in conjunction with the FAA. Now the National Transportation Safety Board will take over.

The NTSB’s job will be to examine the wreckage and attempt to determine if the crash was caused by a defective aircraft part, negligent maintenance, or pilot error. The NTSB concedes, however, that it lacks the manpower, the technical expertise, and the funding to do that job properly on its own. Therefore, as a matter of long-standing policy, it will seek engineering assistance from the companies that manufactured the aircraft components in question. In this case, the NTSB will recruit the help of Cessna Aircraft, which manufactured the aircraft involved in the accident, Cessna N5225J, and Teledyne Continental Motors, which manufactured each of the aircraft’s two 260 horsepower C-310 File Photo by Kensavition.comengines. The NTSB will exclude members of the victims’ families and their technical representatives from the investigation, feeling that they have nothing to offer. (Sad but true.)

Of course, the NTSB’s practice of asking the manufacturers for help – a practice it calls “the party system” — presents a conflict of interest.  After all, the manufacturers themselves might be the ones responsible for the accident. Some say that the NTSB’s party system is akin to asking the suspects for help in solving a crime. Nonetheless, the conflict – discussed further here – is ingrained in all NTSB investigations.

It’s no surprise that most NTSB final reports often favor the manufacturers who have “assisted” the NTSB investigators in their work. But perhaps it doesn’t make any difference because, by federal regulation, the NTSB’s probable cause findings are not binding on anyone. The families are free to conduct their own investigation, and in the event of a lawsuit, the NTSB’s conclusions are given no deference whatever. In fact, in the event of litigation, the NTSB conclusions are not even admissible. Aviation attorneys who conduct their own independent investigations find that the NTSB’s conclusions are wrong about 50% of the time.

In one recent example, a Teledyne Continental engine similar to those installed on N5225J quit
