AD: Bombardier-Rotax

AD NUMBER: 2010-20-23

MANUFACTURER:Bombardier-Rotax GmbH Type 912 F, 912 S, and 914 F Series Reciprocating Engines
SUBJECT: Airworthiness Directive 2010-20-23

SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for certain serial numbers (S/Ns) of Bombardier-Rotax GmbH type 912 F and 914 F series reciprocating engines. That AD currently requires initial and repetitive visual inspections of the engine crankcase for cracks. This AD requires those same inspections, adds the 912 S series to the affected population, adds a test procedure to determine the engine suitability for a special flight permit, and changes applicability from engine S/N to crankcase S/N. This AD results from an increase in the affected crankcase population. The FAA is issuing this AD to prevent oil loss caused by cracks in the engine crankcase, which could lead to in-flight failure of the engine and forced landing.
