Airworthiness Concern Sheet-Piper PA-32 Hoses
Notice Number: NOTC9659
On February 19, 2019, an IA contacted the FAA in regards to the applicable aircraft under AD 2017-14-04. During an inspection, he had noticed that the PA28RT-201 Arrow IV was not listed on the AD, even though it has an identical oil cooler installation as the other PA-28 Arrows with the same engine installation. Since the FAA cannot hold Part 91 owners/operators to the service life limit requirements provided by the manufacturer in the maintenance manual, the AD would need to be updated with any additional models to provide the proper coverage to avoid the unsafe condition with the Type C hoses. In addition, since AD 2017-14-04 only addresses the oil cooler hoses, the FAA is also interested in whether the flying public is still utilizing Type C hoses in their engine compartments to see whether adding any other hose applications (i.e. fuel, turbocharger, etc) to the AD would be necessary to ensure safety is being maintained.
