Airworthiness Directives; Turbomeca 

Makila 2A Turboshaft Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

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 digital engine control units (DECUs) 

used to control MAKILA 2A and MAKILA 

2A1 engines have an ambient pressure (P0) 

sensor with a measurement accuracy that 

may be outside the range required for 

satisfactory functioning of the engines 

throughout the entire operating envelope. In 

certain extreme flight conditions, the lack of 

P0 measurement accuracy could potentially 

cause an engine flameout if the engine is 

operating on a replacement fuel. 

The issue is limited to a batch of 24 

DECUs, of which 23 are known to be still in 

service. Since 01 January 2010, any such 

DECU returned to an approved repair centre 

has had its P0 sensor checked and replaced 

as necessary. 

We are issuing this AD to prevent an 

uncommanded engine in-flight 

shutdown which could result in a 

forced autorotation landing or accident. 

DATES: This AD becomes effective May 

17, 2010. 

We must receive comments on this 

AD by June 1, 2010. 

ADDRESSES: You may send comments by 

any of the following methods:

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the

and MAKILA 2A1 engines have an ambient 

pressure (P0) sensor with a measurement 

accuracy that may be outside the range
