2009-12-14 Aeromot-Industria Mecanico Metalurgica ltda.: Amendment 39-15937; Docket No. FAA-2009-0323; Directorate Identifier 2009-CE- 012-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective July 17, 2009.
Affected ADs
(b) None.
Applicability
(c) 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.
Subject
(d) Air Transport Association of America (ATA) Code 73: Engine Fuel & Control.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
It has been found that the coolant liquid EVANS NPG + is a flammable fluid. The engine liquid cooling system of the affected Aeromot aircrafts is not designed to operate with flammable liquids. Therefore, there is an unacceptable engine fire risk associated with the use of EVANS NPG + fluid.
Since this condition may occur in other aircraft of the same type and affects flight safety, an immediate corrective action is required. Thus, sufficient reason exists to request compliance with this AD in the indicated time limit without prior notice.
The MCAI requires replacement of the EVANS NPG + coolant liquid, application of new red lines on the engine cylinder head temperature gauge, replacement of the engine radiator cap, and insertion of information into the airplane flight manual (AFM).
Actions and Compliance
(f) 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:
(1) Replace the EVANS NPG + cooling liquid with a conventional, FAA-approved coolant for the ROTAX 912 and 914 series engines.
(2) Apply a new red line marking on the engine cylinder head temperature gauge at 120 degrees C/248 degrees F.
(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. B, dated December 20, 2006, into the AFM, Limitations section, Section 2 on item 2.4, power plant, fuel and oil limitations and item 2.5, power plant instrument markings.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information as follows: No differences.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Greg Davison, Glider Program Manager, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4130; fax: (816) 329-4090. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
