Special Conditions: Bombardier Inc. Model CL-600-2E25 Airplane, Interaction of Systems and Structures
These special conditions are issued for the Bombardier Inc. Model CL-600-2E25 airplane. This airplane will have a novel or unusual design feature associated with the rudder-traveler limiting system controlling the command-by-wire (CBW) rudder. This system can serve to alleviate loads in the airframe but, in a failure state, can create loads in the airframe. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Special Conditions: Bombardier Inc. Model CL-600-2E25 Airplane, Operation Without Normal Electrical Power
These special conditions are issued for the Bombardier Inc. Model CL-600-2E25 airplane. This airplane will have a novel or unusual design feature associated with a command-by-wire (CBW) rudder-control system, which requires a source of continuous electrical power to operate the control system. The current 14 CFR part 25.1351(d), ``Operation without normal electrical power,'' requires safe operation in VFR conditions for at least five minutes with inoperative normal electrical power. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
Airworthiness Directives; McDonnell Douglas Corporation Model MD-11 and MD-11F Airplanes
We are revising an earlier proposed airworthiness directive (AD) for the products listed above. That NPRM proposed a one-time inspection to detect damage of the wire assemblies of the tail tank fuel system, a wiring change, and corrective actions if necessary. That NPRM was prompted by fuel system reviews conducted by the manufacturer. This action revises that NPRM by adding, for certain airplanes, a general visual inspection for correct installation of the self- adhering, high-temperature electrical insulation tape; installation of a wire assembly support bracket and routing wire assembly; changing wire supports; and installation of a wire protection bracket. We are proposing this supplemental NPRM to detect and correct a potential of ignition sources inside fuel tanks, which, in combination with flammable vapors, could result in a fuel tank fire or explosion, and consequent loss of the airplane.
Commercial Space Transportation Advisory Committee; Renewal
Pursuant to Section 14(a)(2)(A) of the Federal Advisory Committee Act (Pub. L. 92-463, 5 U.S.C. App. 2), and 5 USC552b (c), and in accordance with Sec. 102-3.65, Title 41 of the Code of Federal Regulations, notice is hereby given that the Commercial Space Transportation Advisory Committee (COMSTAC) has been renewed for a 2- year period beginning November 17, 2010. The primary purpose of the Committee is to provide information, advice, and recommendations to the U.S. Department of Transportation (DOT) on matters concerning the U.S. commercial space transportation industry. The primary goals of the Committee are to evaluate economic, technological, and institutional developments relating to the industry; to provide a forum for the discussion of problems involving the relationship between industry activities and government requirements; and to make recommendations to DOT on issues and approaches for Federal policies and programs regarding the industry. The Committee will operate in accordance with the rules of the Federal Advisory Committee Act and the Department of Transportation, FAA Committee Management Order (1110.30C).
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model S-70A and S-70C Helicopters
This amendment adopts a new airworthiness directive (AD) for the Sikorsky Model S-70A and S-70C helicopters. This AD requires an ultrasonic test (UT) inspection of the tail gearbox output bevel gear (gear) for a crack. If you find a crack, replacing the gear with an airworthy gear is required before further flight. This AD is prompted by three gear cracking incidents, one of which resulted in the tail rotor separating from the helicopter. The actions specified by this AD are intended to detect a crack in the gear to prevent a tail rotor separating, loss of tail rotor control, and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France (ECF) Model SA330F, G, and J; and AS332C, L, L1, and L2 Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified ECF model helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD states that EASA received a report of a rear hinged door on a Model AS332L1 helicopter opening in flight without loss of the door. Examinations revealed incorrect positioning of a door catch that resulted in incorrect locking and uncontrolled opening of the door. This condition, if not detected and corrected, can lead to the loss of the hinged door in flight, damage to the main or tail rotor blades, and subsequent loss of control of the helicopter.
Airworthiness Directives; General Electric Company (GE) CT7-9C and -9C3 Turboprop Engines
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires inspecting certain serial number (S/N) gas generator turbine (GGT) shafts for nonconforming land balance-cuts, and if found, removing the shaft from service. This AD was prompted by reports of a manufacturing quality problem. We are issuing this AD to detect nonconforming GGT shaft land balance-cuts, which could result in the shaft failing before its published life limit, and which could result in an uncontained engine failure and damage to the airplane.
Airworthiness Directives; Viking Air Limited (Type Certificate Previously Held by Bombardier, Inc.) Model DHC-7 Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; The Boeing Company Model 777-200, -200LR, -300, and -300ER Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires removing and repairing the sealant at the four lower corners of the wing center section and the four lower t-chord segment gaps on each side of the wing center section. This AD results from reports of fuel leakage from the center tank. We are issuing this AD to detect and correct improperly applied sealant, which could result in the disbonding and displacing of sealant, and consequent fuel leaks. On the ground, uncontained fuel leakage could result in pooling, and pooling combined with an ignition source could result in a fire.
Airworthiness Directives; Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440), CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900) Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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:
Airworthiness Directives; Various Aircraft Equipped With Rotax Aircraft Engines 912 A Series Engines
We are adopting a new 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:
