AD 2012-17-01 Airworthiness Directives; Goodyear Aviation Tires

Models named: CL-600-2B19. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to the following new Goodyear Aviation Tires (retreads are not affected by this AD), installed on various transport category airplanes, including but not limited to Bombardier, Inc. Model CL-600-2B19 airplanes: (1) New tire part number (P/N) 299K63-1 with the following specifications: (i) Tire size: H29x9.0-15; (ii) Ply rating: 16PR; and (iii) Speed rating: 210 miles per hour. (2) Serial numbers (S/N) 01867xxx through 02737xxx with the following specifications: (i) The 5th digit of the serial number must be a “7”; and (ii) “XXX” can be any combination of three single digit numbers.

Unless already done, do the following actions in accordance with Goodyear Aviation Service Bulletin 2012-32-001, dated April 19, 2012. (1) Within the next 5 flight cycles (landings) after September 13, 2012 (the effective date of this AD), inspect the main landing gear tires, P/N 299K63-1, to determine if an affected S/N tire, as specified in paragraph (c) of this AD, is installed. A review of the airplane maintenance records is acceptable in lieu of this inspection if the P/N and S/N of the tires installed can be positively determined from that review. Operators that do not maintain landing records can determine the number of landings by dividing the number of airplane hours time-in-service (TIS) by two. (2) Before further flight after the inspection required in paragraph (f)(1) of this AD, replace any tire that has an affected serial number. (3) As of September 13, 2012 (the effective date of this AD), do not install any main landing gear tire, P/N 299K63-1, that has an affected serial number specified in paragraph (c)(2) of this AD.

The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Atlanta Aircraft Certification Office (ACO), 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: Samuel Belete, Aerospace Engineer, FAA, Atlanta ACO, 1701 Columbia Avenue, College Park, Georgia 30337; phone: (404) 474-5580; fax: (404) 474-5606; email: samuel.belete@faa.gov. 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, a federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to be approximately 5 minutes per response, including the time for reviewing instructions, completing and reviewing the collection of information. All responses to this collection of information are mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at: 800 Independence Ave. SW., Washington, DC 20591, Attn: Information Collection Clearance Officer, AES-200.

This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as tire tread separations and tread-area bulges on the main landing gear tires due to low adhesion in the tread should area. We are issuing this AD to prevent failure of the main landing gear tires during takeoff or landing, which could cause damage to the airplane structure, flaps, engine, and wheel well and result in reduced controllability of the airplane.
