Airworthiness Directive 2001-06-14
one-timeAirworthiness Directives; Cessna Aircraft Company Models 172R and 172S Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD) that applies to certain Cessna Aircraft Company (Cessna) Models 172R and 172S airplanes. This AD requires a one-time inspection for proper engine idle speed and fuel control mixture setting and adjustment, as necessary. This AD also requires incorporating engine operating procedures into the pilots operating handbook (POH) and FAA-approved airplane flight manual (AFM). This AD is the result of reports of rough engine operation because of an over-rich fuel mixture (improper fuel flow settings). The actions specified by this AD are intended to detect and correct such improper fuel flow settings, which could result in rough engine operation or engine stoppage. This over-rich fuel mixture also contributes to the engine not restarting during flight when using published in-flight restart procedures.
Which aircraft AD 2001-06-14 applies to
Applies to Models 172R and 172S, all serial numbers, certificated in any category, to correct an over-rich fuel mixture (improper fuel flow setting) that could cause rough engine operation, engine stoppage, or failure to restart in flight; requires inspection/adjustment of engine idle speed and mixture setting per pilot or mechanic procedure.
Whether AD 2001-06-14 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
