AD: Turbomeca S.A. Arriel 2B Turboshaft Engines

AD NUMBER: 2011-24-07

MANUFACTURER: Turbomeca S.A. Arriel 2B Turboshaft Engines
SUBJECT: Airworthiness Directive 2011-24-07
ACTION: Final Rule, Request for Comments

SUMMARY: 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:

Non-conformities on adjustment of some hydromechanical units (HMUs) have been reported by a Turbomeca repair centre. The technical investigations carried out by
Turbomeca are showing that only a limited number of HMUs are potentially affected by this non-conformity to HMU adjustment. Twenty nine HMUs have been identified with the non-conformities. We are issuing this AD to prevent an uncommanded inflight shutdown, which could result in an emergency autorotation landing.

DATES: This AD becomes effective December 14, 2011. The FAA must receive comments on this AD by December 29, 2011
