Federal Aviation Administration August 16, 2006 – Federal Register Recent Federal Regulation Documents

The FAA proposes to adopt a new airworthiness directive (AD) for certain Learjet Model 23, 24, 24A, 24B, 24B-A, 24C, 24D, 24D-A, 24E, 24F, 24F-A, 25, 25A, 25B, 25C, 25D, 25F, 28, 29, 31, 31A, 35, 35A (C-21A), 36, 36A, 55, 55B, and 55C airplanes. This proposed AD would require modifying the left- and right-hand standby fuel pump switches. This proposed AD would also require revising the Emergency and Abnormal Procedures sections of the airplane flight manual to advise the flightcrew of the proper procedures to follow in the event of failure of the standby fuel pump to shut off. This proposed AD results from a report of inadvertent operation of a standby fuel pump due to an electrical system malfunction. We are proposing this AD to prevent this inadvertent operation, which could result in inadvertent fuel transfer by the left or right wing fuel system and subsequent over-limit fuel imbalance between the left and right wing fuel loads. This imbalance could affect lateral control of the airplane which could result in reduced controllability.

This rule establishes a Class E surface area airspace extending upward from 700 feet above the surface at Higginsville, MO. The effect of this rule is to provide appropriate controlled Class E airspace for aircraft departing from and executing instrument approach procedures to Higginsville Industrial Municipal Airport, MO and to segregate aircraft using instrument approach procedures in instrument conditions from aircraft operating in visual conditions.
