Plain English Summary

2/10 complexity

What this is: A mandatory safety instruction (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority (CASA) requiring specific maintenance work on certain Piper Cherokee aeroplanes.

Who it affects: Owners and operators of specific Piper PA-28 models:

PA-28-150, PA-28-160, and PA-28-180 (serial numbers 28-1761 to 28-7505259)
PA-28-181 (serial numbers 28-7690001 to 28-7790103)
PA-28-235 (serial numbers 28-10001 to 28-7310176)

What must be done: The lower cowl drain (an opening that allows water and debris to exit the engine compartment) must be inspected and modified according to technical instructions in Piper Service Letter No. 796.

When: The work must be completed within 100 hours of flight time after 31 May 1977.

Why it matters: This prevents potential safety issues such as engine cooling problems or corrosion caused by blocked or inadequate drainage in the engine cowling.
