The Federal Register for Monday, February 2, includes an Airworthiness Directive issued by FAA ordering an estimated $15 Million worth of inspections and repairs on 34,013 older small aircraft manufactured by Piper Aircraft, Inc. Included are the single-engine PA-28 and PA-32 models, and the PA-34 and PA-44 (both twin-engine models). The safety issue was corrosion of stabilator control cables, as identified on these four Piper models. The AD applies to those aircraft in service for 15-years or more. For the record, the airplane service manuals include a special inspection with a requirement that the cable be replaced if any corrosion is found.
- 4/7/11: a PA32 at Sundance Airport (HSD), in Oklahoma City. The pilot had just taken off when the cable snapped, causing the nose to point downward. He impacted the runway, did another hard bounce, and came to a stop with substantial damage but no injuries. The pilot and a passenger had been practicing touch-and-go landings.
- 3/14/12: a PA32 at Warrenton, VA (HWY). A commercial pilot and flight instructor had departed the Manassas airport (HEF) earlier to practice maneuvers in a local practice area. They then went to Warrenton airport with intentions to do closed pattern practice. One landing was done and, on landing flare for the second landing, the pilot heard a loud ‘boom’ and the airplane’s nose dropped.
This analysis by aiREFORM does not (yet) include a closer look at the larger NTSB accident history, to determine extent of damage and numbers of fatalities during the decade-plus delay.
NTSB’s statement supporting the proposal was summarized as follows:
It is good to see NTSB not only making Safety Recommendations, but also following through until they are implemented. Back in 2002, when NTSB prematurely ‘Closed’ their 2001 Safety Recommendation, they were clearly operating with a deficient concern for safety.
Also, it is a promising development, that FAA has chosen to finalize this AD. Doing so will likely save at least a few dozen lives in the next decade. The average cost to the owners of these aircraft will be less than $500 — money very well spent to not be confronted with the physical hazard, or the intense emotional distress, of a sudden loss of stabilator control.
Hopefully, this marks a new direction for FAA, in which they will quickly and decisively address safety issues for PA28’s, Boeing 787’s, and all types of aircraft.
