AD 2010-18-05 Airworthiness Directives; Aircraft Industries a.s. (Type Certificate G24EU Previously Held by LETECKÉ ZÁVODY a.s. and LET Aeronautical Works) Model L-13 Blanik Gliders

This AD applies to Aircraft Industries a.s. L-13 Blanik gliders, all serial numbers, certificated in any category.

To address this problem, before further flight after August 30, 2010 (the effective date of this AD), incorporate an FAA-approved inspection and/or modification program developed specifically for this AD. Corrective action is considered FAA-approved if it is 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. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: The MCAI requires the owner/operator to submit data regarding certain operations including aerobatic operations, to the European Aviation Safety Agency (EASA) and Aircraft Industries, a.s. so they can determine whether further flight is permitted. The FAA does not require such data to be collected for operations in the United States. The FAA is relying on an inspection and/or modification program approved specifically for this AD to detect and correct cracks before further flight. Until such a program is approved, owners/operators may apply for an alternative method of compliance (AMOC) following 14 CFR 39.19 described in paragraph (f)(1) of this AD. The FAA will work with EASA and Aircraft Industries a.s. to determine if an acceptable level of safety is achieved with the AMOC proposal. Other FAA AD Provisions (f) 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, Aerospace Engineer, 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. Special Flight Permit (g) Under 14 CFR part 39.23, we are limiting the special flight permits for this AD by prohibiting aerobatic maneuvers. Related Information (h) Refer to MCAI EASA Emergency AD No. 2010-0160-E, dated July 30, 2010, for related information.
