Another AD on for Engine oil Piaggio P180

AD 2010-21-08 Piaggio Aero P-180

SUMMARY: We are adopting a new airworthiness directive (AD) for the products
listed above. This AD results from mandatory continuing airworthiness
information (MCAI) issued by an aviation authority of another country to
identify and correct an unsafe condition on an aviation product.

The MCAI describes the unsafe condition as:
Some cases of failure of engine oil dipsticks, installed on Pratt & Whitney
Canada (P&WC) PT6A66 and PT6A66B engines, were detected on P.180 aeroplanes;
such failures, due to moisture penetration into the dipstick and subsequent
corrosion, can cause incorrect reading of the engine oil low level on the
Refuel/Ground Test Panel.

If left uncorrected, this situation could lead to in-flight engine
failure(s). We are issuing this AD
to require actions to correct the unsafe condition on these products.

DATES: This AD becomes effective November 18, 2010.
