Introduction

This Special Airworthiness Information Bulletin alerts you, owners and operators of Agusta S.p.A. Model A119 helicopters with an air conditioning compressor installed by Air Comm Corporation Supplemental Type Certificate (STC) Number SR00463DE of an issue with the compressor drive belt.

TABLE 1 Service Bulletin Title Date SB A119- 3024, Revision B Air Conditioner Oil Cooler Inlet Screen Assembly, Engine Governor Control Guard August 1, 2005 SB A119- 306, Revision C Air Conditioner Drive Belt Change from Cogged to Poly-V Belt August 1, 2005

Background

Air Comm Corporation recently issued service bulletins (SBs table 1) on the Agusta A119 helicopter, which is the result of a recent A119 incident where the pilot observed high oil temperatures. The pilot made an immediate landing and found the air conditioner compressor drive belt had broken. This resulted in substantial damage to the oil cooler blower fan blades. In addition, the failed belt had damaged the mechanical engine governor control cable.

Recommendation

To prevent any further failures or potential injury, we recommend that you follow the information described in Air Comm’s attached SBs.
