Safety Enhancements, Certification of Airports
This rulemaking amends regulations pertaining to certification of airports to clarify that the applicability of these regulations is based only on passenger seats in passenger-carrying operations as determined by either the regulations or the aircraft type certificate. This final rule also adds a new section that prohibits fraudulent or intentionally false statements concerning an airport operating certificate. Finally, this final rule adopts administrative changes for internal consistency, or to codify existing industry practice. These changes are necessary to clarify the applicability language, and ensure the reliability of records maintained by a certificate holder and reviewed by the FAA. Lastly, this final rule changes the definition of joint-use airport to correspond with statutory authority.
Airworthiness Directives; Various Aircraft Equipped With Wing Lift Struts
We propose to revise an existing airworthiness directive (AD) that applies to certain aircraft equipped with wing lift struts. The existing AD currently requires repetitively inspecting the wing lift struts for corrosion; repetitively inspecting the wing lift strut forks for cracks; replacing any corroded wing lift strut; replacing any cracked wing lift strut fork; and repetitively replacing the wing lift strut forks at a specified time for certain airplanes. The existing AD also currently requires incorporating a ``NO STEP'' placard on the wing lift strut. Since we issued that AD, we have been informed that paragraph (c) in the existing AD is being misinterpreted and causing confusion. This proposed AD would clarify the intent of the language currently in paragraph (c) of the existing AD and would retain all other requirements of the existing AD. We are proposing this AD to correct the unsafe condition on these products.
Airworthiness Directives; the Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-200B, 747-300, 747-400, 747-400D, 747-400F series airplanes, and Model 767 series airplanes, powered by General Electric (GE) CF6-80C2 engines. This proposed AD was prompted by reports of failure of the electro-mechanical brake flex shaft (short flexshaft) of the thrust reverser actuation system (TRAS). This proposed AD would require replacing the short flexshaft on each engine with a new short flexshaft, testing of the electro-mechanical brake and center drive unit (CDU) cone brake to verify the holding torque, and performing related investigative and corrective actions if necessary. We are proposing this AD to prevent an uncommanded in-flight thrust reverser deployment and consequent loss of control of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Airplanes Model 737-100, -200, -200C, -300, -400, -500, -600, -700, -700C, -800, and -900 series airplanes. This proposed AD was prompted by a report that the seat track attachment of body station 520 flexible joint is structurally deficient in resisting a 9g forward emergency load condition in certain seating configurations. This proposed AD would require replacing the pivot link assembly on certain seats, and modifying or replacing the seat track link assemblies on certain seats. Also, for certain airplanes, this proposed AD would require installing a new seat track link assembly. We are proposing this AD to prevent seat detachment in an emergency landing, which could cause injury to occupants of the passenger compartment and affect emergency egress.
