FAA orders Aviat Husky stabilizer inspections

An airworthiness directive that took effect September 1 mandates inspection of horizontal stabilizer components of all aircraft in the Aviat Aircraft A–1, A–1A, A–1B, A–1C-180, and A–1C-200 line of single-engine airplanes.

The FAA issued the AD, which calls for “repetitive inspections of the forward horizontal stabilizer support assembly and the rear horizontal stabilizer support tube” of Aviat Husky models and reporting the results to the FAA in response to field reports that noted fatigue failures of both components.

“Failure of either the forward or rear support transfers loads to the other support, increasing the likelihood that both could fail. This condition, if not addressed, could result in stabilizer departure and loss of airplane control,” the AD notes.

The AD affects an estimated 941 aircraft and was issued as a final rule without being preceded by a public comment period.

However, the FAA said it will accept comments until October 1, and could modify the AD as a result.

The FAA estimated total costs of the inspections, to be conducted in accordance with Aviat Service Bulletin No. 28, Revision A, dated April 2, 2015, at $152.50 per aircraft. Differences from the service bulletin include the AD’s applicability to all serial numbers of the listed models and the requirement for “both initial and repetitive inspections.”

See the AD for details on how to submit comments online, by mail, or by other means.
