We are superseding an existing 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:
Do the following unless already done:
(1) Before further flight after April 1, 2008 (the compliance date retained from AD 2008-06-15), inspect the balloon burner to determine whether it has a hose from the affected batch of hoses following Lindstrand Hot Air Balloons Ltd. Service Bulletin No. 11, Issue 1, dated September 24, 2007.
(2) If as a result of the inspection required by (f)(1) of this AD you find a hose from the affected batch, before further flight, inspect for leaks and conduct a pressure test following Lindstrand Hot Air Balloons Ltd. Service Bulletin No. 11, Issue 1, dated September 24, 2007, and repetitively thereafter inspect and conduct a pressure test at intervals not to exceed 10 hours time-in-service.
(3) If as a result of any inspection or test required by (f)(2) of this AD you find a defective hose, before further flight, replace it and the end fitting with a new hose and new end fitting following FAA-approved instructions. The Lindstrand Balloons Ltd. maintenance manual contains FAA-approved instructions. This action terminates the repetitive requirement in (f)(2) of this AD.
(4) Unless already done, within 12 months after July 23, 2008 (the effective date of this AD), replace any hose from the affected batch with a new hose and end fitting following FAA-approved instructions. The Lindstrand Balloons Ltd. maintenance manual contains FAA-approved instructions. After doing this replacement, no further action is required by this AD.
Note 1: At any time after July 23, 2008 (the effective date of this AD), you may replace the hose and end fitting to terminate the repetitive inspection and testing requirements of this AD.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
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.
