Summary
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed to rescind airworthiness directive (AD) 2008-06-03, which applies to certain The Boeing Company Model 737-600, -700, -700C, -800 and -900 series airplanes; and Model 757-200, -200PF, -200CB, and -300 series airplanes. The NPRM would have rescinded AD 2008-06-03, which requires an inspection to determine if certain motor-operated shutoff valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. AD 2008-06-03 also requires revising the Airworthiness Limitations (AWLs) section of the Instructions for Continued Airworthiness to incorporate certain AWLs. Since the NPRM was issued, we have determined that it does not adequately address the safety concerns. Accordingly, the NPRM is withdrawn.
