Superseded. A later AD replaced this one: AD 2008-13-05. Comply with the one in force.
This AD applies to Models 42A, 56A, 60A, 69A, 77A, 90A, 105A, 120A, 150A, 180A, 210A, 240A, 260A, and 310A balloons that are:
(i) Certificated in any category; and
(ii) Equipped with burners with serial numbers BU502 through BU792, except BU507, BU511, BU512, BU614, BU643, BU655, BU656, BU719, BU723, BU746, BU749, BU752, BU754, BU762, BU779, BU781, BU785, BU787, and BU789.
We are adopting a new airworthiness directive (AD) for the products listed above. 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:
Unless already done, do the following actions:
(1) Before further flight as of April 1, 2008 (the effective date of this AD) 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) As a result of the inspection required by (f)(1) of this AD, if 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) As a result of any inspection or test required by (f)(2) of this AD, if you find a defective hose, replace it and the end fitting with a new hose and new end fitting before further flight. This action terminates the repetitive requirement in (f)(2) of this AD.
Note 1: You may replace the hose and end fitting at any time 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: (1) The MCAI and the service information specify repetitive inspections if no leaks are detected during the initial required inspection, until the next annual inspection, at which time replacing the hose and end fitting is required. (2) This AD is considered an interim action because we are not including the mandatory replacement terminating action in this AD (replacement is only required by this AD if a defective hose is found in an inspection or test). The Administrative Procedure Act does not permit the FAA to “bootstrap” a long-term requirement into an urgent safety of flight action where the rule becomes effective at the same time the public has the opportunity to comment. The short-term action and the long-term action are analyzed separately for justification to bypass prior public notice. (3) After issuing this AD, we may initiate further AD action (notice of proposed rulemaking followed by a final rule) to require a terminating action to the repetitive inspection and test.
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.
