Plain English Summary

1/10 complexity

What this is: An airworthiness directive (a mandatory safety order) requiring owners of specific Cessna aircraft to fix a potentially dangerous defect in the engine oil system.

Who it affects: Owners of specific Cessna 172 and F172 aeroplanes with the following serial numbers:

Model 172: S/N 17274010 to 17274579 and 17274587
Model F172: S/N F17202040 to F17202149

What must be done: Aircraft owners must carry out the inspection and repair actions described in the manufacturer's document "Cessna Service Information Letter SE81-5" to address the oil pressure line.

When: Within 100 hours of "time in service" (flying time) after 31 May 1981.

Why it matters: The oil pressure line on these aircraft could fracture (crack), causing engine oil to leak out. This could lead to engine failure and loss of control of the aircraft.
