Aeromot-Industria Mecanico Metalurgica ltda. Model AMT-200 and AMT-300 Series Gliders
This AD applies to all serial numbers of the following gliders that are certificated in any category:
(1) Model AMT-100 gliders as modified to Model AMT-200 gliders; and
(2) Models AMT-200, AMT-200S, and AMT-300 gliders.
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:
Unless already done, do the following actions within the next 20 hours time-in-service after July 17, 2009 (the effective date of this AD) or within the next 30 days after July 17, 2009 (the effective date of this AD), whichever occurs first, following AEROMOT Alert Service Bulletin No. 200-71-106, Rev. B, dated December 20, 2006; ROTAX Aircraft Engines Mandatory Service Bulletin SB-912-043 R2/SB-914-029 R2, dated November 10, 2006; and ROTAX Aircraft Engines Service Instruction SI-912-016/SI-914-019, dated August 28, 2006:

(3) Replace the radiator cap part number (P/N) 922075 from the affected engines with a new radiator cap P/N 922070.
(4) Insert into the AFM Limitations section an amendment to include the new operation limit of the cylinder head temperature to 120 degrees C/248 degrees F by inserting a copy of AEROMOT Alert Service Bulletin No. 200-71-106, Rev.
