AD NUMBER: 2010-11-09R1

PRODUCT: TAE models TAE 125-01 and TAE 125-02-99 reciprocating engines installed on, but not limited to, Diamond Aircraft Industries Model DA 42 airplanes.
SUBJECT: Airworthiness Directive 2010-11-09R1
ACTION: Final Rule

SUMMARY: The FAA is revising an existing (AD) for TAE models TAE 125-01 and TAE 125-02-99 reciprocating engines installed on, but not limited to, Diamond Aircraft Industries Model DA 42 airplanes. That AD currently requires initial and repetitive replacements of proportional pressure reducing valves (PPRVs) (also known as propeller control valves).

This new AD relaxes the repetitive replacement interval from a 300-hour interval to a 600-hour interval for PPRVs, P/N 05-7212-E002801, on TAE 125-02-99 engine. This AD was prompted by TAE increasing the life of the PPRV, part number (P/N) 05-7212-E002801, on TAE 125-02-99 engines from 300 to 600 hours. The FAA is issuing this AD to prevent engine in-flight shutdown, possibly resulting in reduced control of the aircraft.

DATES: This AD is effective April 11, 2012.
