The FAA has issued five special airworthiness information bulletins (SAIBs) to address potential corrosion problems on a variety of Piper aircraft.
Each SAIB highlighted specific problem areas on the Pipers, but all the bulletins urged owners and operators to “increase their focus on inspections” provided in the aircraft service manuals.
The new SAIBs address the following Piper aircraft corrosion risks:
The average aircraft in the general aviation fleet is 30 years old—but age alone does not tell the story of an aircraft’s susceptibility to corrosion or other problems. Each aircraft’s condition depends on numerous factors including how it is used, stored, and maintained.
The Air Safety Institute offers an Aging Aircraft interactive course that reviews maintenance and ownership strategies for keeping older aircraft flying, shows examples of problems such as different kinds of corrosion and metal fatigue, and discusses the general effects of aging on aircraft. Significant input from the FAA’s Small Airplane Directorate and industry type clubs was used to develop several manufacturer-specific tracks for most common makes of aircraft.
SAIBs are not mandatory, but are issued by the FAA in response to reported service data, and offer valuable guidance on aircraft care to owners and operators.

Beringer Wheels and Brakes announced the availability of several types of aircraft wheels on July 29 at EAA AirVenture in Oshkosh, Wisconsin, and said a new anti-groundloop tailwheel design is forthcoming.
The widespread presence of angle-of-attack indicators in general aviation aircraft could reduce fatal loss-of-control accidents caused by inadvertent stalls, said the FAA.
Flight Design says production and testing of its four-seat C4 is on target despite the ongoing conflict in Ukraine.
