Another Zodiac In-Flight Breakup Triggers an NSTB "I told you so"

Zodiac AircraftThis past April, the NTSB called upon the FAA to ground the entire fleet of Zodiac aircraft because their wings tend to fall off in mid-flight.  As it turns out, a defect in the Zodiac's design induces an aerodynamic phenomenon known as flutter.  Flutter can destroy a wing or other control surface in a matter of seconds.  This well-known, dangerous, but rare condition is shown occurring in the tail surfaces of other aircraft types here and here

When the NTSB's issued its "urgent recommendation," a total of ten people had already been killed in Zodiacs due to flutter-induced failures.  Back then, the NTSB was under heavy fire for sitting on a long list of NTSB recommendations pertaining to a number of different aviation industry sectors while lives were being lost. Because of that, I figured that this was one recommendation the FAA would act on, and fast.

The FAA will see Zodiac's manufacturer as an easy target and move against it -- if for no other reason than to quiet its critics.

I was wrong.  The FAA refused to ground the aircraft.  Even I was surprised.

Of course, it was just a matter of time.  On November 6, another Zodiac crashed in Arkansas.   It looks like another flutter-induced failure.  That brings the death toll to 11.  On November 13, the NTSB issued an official "I told you so."

The Safety Board's urgent recommendation to the FAA was to "prohibit further flight of the Zodiac CH-601XL, both special light sport aircraft and experimental, until such time that the FAA determines that the CH-601XL has adequate protection from flutter." The FAA replied in July that they lacked "adequate justification to take immediate certificate action to ground the entire fleet." 

The NTSB's unstated question:  Just how many deaths are required before the FAA finds "adequate justification" to act?

More Zodiac Victims File Suit

The families of the victims of the Zodiac crash near Oakdale, California, have filed suit against the aircraft's maker, Zenith Aircraft, alleging that the Zodiac's design is defective. The Zodiac is the two-seat aircraft whose wings tend to break off in flight due to a design-induced aerodynamic phenomenon known as flutter.  That appears to be exactly whatZodiac happened in the Oakdale crash. The design has caused at least 10 deaths so far. 

According to the Modesto Bee, Zenith Aircraft is blaming the pilot and passenger for getting into the airplane it designed.

 Zenith Aircraft said the crash was caused by the "negligence" of [the pilot and his passenger]. The company said both had "full appreciation" of the risks involved.

As discussed here, months ago the NTSB called upon the FAA to ground all Zodiacs. The FAA, however, has yet to do so.  Unfortunately, the NTSB has no power to ground an aircraft on its own.  It doesn't matter how bad the design of the aircraft is; only the FAA can ground a fleet. 

The FAA refuses to act, and Zenith Aircraft won't accept responsibility for the fatal flaws in its aircraft's design.  Lawsuits brought by aviation accident lawyers like the families' lawyers in this case seem to be the only way to prevent others from being killed in the Zodiac. 

OSC: FAA Ignoring EMS Helicopter Dangers For Fear of Negative Publicity

The FAA is supposed to use its regulatory powers to promote aviation safety.  Over the years, however, it seems to have become too bureaucratic and conflicted to take decisive action when it counts most.  Examples:FAA

Now, there's more.  In 2008, an FAA inspector determined that nearly half of the nation's EMS helicopter fleet--about 300 aircraft--have improperly installed night vision systems. As installed, the systems are a hazard to the air ambulance crews and the patients they carry.  The inspector felt the aircraft should be grounded until they were fixed.  The FAA initially agreed, but then changed its mind.  Apparently,  the FAA decided to look the other way because of the "negative publicity" a grounding would generate.

Huh?  Since when should the FAA be concerned more with negative publicity than with safety?

Recently, the United States Office of Special Counsel became involved.  Special Counsel, however, has been unable to get the FAA to respond to its inquiries.  So it has taken the unusual step of writing to President Obama.

[The United States Office of Special Counsel] found a substantial likelihood that FAA officials and employees engaged in violation of law, rule or regulation, gross mismanagement and an abuse of authority, all of which contributed to a substantial and specific danger to public safety.

The Office of Special Counsel appears more interested in EMS Helicopter safety than does the FAA.  We'll see what happens next.EMSHelicopterOSC

NTSB to FAA: Ground the Zodiac Fleet

Zodiac CH-601XL

Today the NTSB issued an "urgent" safety recommendation, asking the FAA to immediately ground all Zodiac CH-601XL aircraft.  The reason:  their wings tend to fall off.  So far, six have broken up in flight, causing 10 fatalities.  The NTSB suspects that the design of the aircraft induces "flutter"-- an aerodynamic phenomenon that can destroy an aircraft in seconds.  This short NASA video depicts flutter nearly destroying the tail on a Piper Twin Comanche.

Will the FAA act on this recommendation or, like it has with regard to so many other NTSB recommendations, simply ignore it?  I'm betting that this is one the FAA will act on.  As I've noted before, the FAA has been under increasing fire for sitting on NTSB recommendations while lives are lost. The FAA will see Zodiac's manufacturer as an easy target and move against it -- if for no other reason than to quiet its critics.
