Plain English Summary

2/10 complexity

What this is: An Airworthiness Directive (AD) — a mandatory safety order issued by the Civil Aviation Safety Authority (CASA) that aircraft owners must follow to keep their planes legally airworthy.

What it requires: Owners of specific Piper Cherokee Six aircraft (model PA-32-260 with serial numbers from 32-01 to 32-7600023) must inspect and modify the lower cowl drain — a drainage hole in the engine compartment cowling.

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

Why it matters: Cowl drains prevent moisture, debris, and potentially dangerous gases (like carbon monoxide) from accumulating in the engine compartment. This directive likely addresses a design flaw or safety risk identified by the manufacturer (referenced in Piper Service Letter No. 796).

Who is affected: Operators and owners of the specific Piper aircraft listed above.
