Airworthiness Directive · Amendment 39-16418 · Wings
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.
We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. This AD results from 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:
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.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
