Document Number: 2011-27807
Type: Proposed Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to modify Class D airspace at Santa Monica Municipal Airport, CA, to accommodate aircraft departing and arriving under Instrument Flight Rules (IFR) at Santa Monica Municipal Airport. This action is a result of the FAA's biennial review, along with a study of the Santa Monica Municipal Airport airspace area that would further enhance the safety and management of aircraft operations at the airport.
Airworthiness Directives; Erickson Air-Crane Incorporated Model S-64F Helicopters
Document Number: 2011-27775
Type: Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for the Erickson Air-Crane (Erickson Air-Crane) Model S-64F helicopters. The amendment requires, at specified intervals, certain inspections of the rotating swashplate assembly (swashplate) for a crack. If a crack is found, this AD also requires, before further flight, replacing the swashplate with an airworthy swashplate. This AD is prompted by a report from the manufacturer of a swashplate cracking during fatigue testing. We are issuing this AD to prevent loss of a swashplate due to a fatigue crack, loss of control of the main rotor system, and subsequent loss of control of the helicopter.
Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Model S-92A Helicopters
Document Number: 2011-27773
Type: Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts a new airworthiness directive (AD) for Sikorsky Model S-92A helicopters. This action requires making pen and ink changes, inserting a copy of this AD, or inserting specified temporary revisions into the Limitations section of the Rotorcraft Flight Manual (RFM) limiting the maximum rolling groundspeed for a normal landing or takeoff from 65 knots to 50 knots for helicopters with a certain serial-numbered landing gear retract actuator (actuator). Instead of limiting the groundspeed, replacing the affected actuator with a modified actuator is terminating action for the requirements of this AD. This amendment is prompted by a report of a main landing gear that would not retract. The manufacturer reports that certain actuators were manufactured with down-lock keys that did not meet the specified minimum hardness requirements. This condition, if not corrected, could lead to a landing gear collapse following a roll- on landing that exceeds 50 knots groundspeed. These actions are intended to prevent collapse of a landing gear and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France (Eurocopter) Model EC225LP Helicopters
Document Number: 2011-27771
Type: Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts a new airworthiness directive (AD) for the Eurocopter Model EC225LP helicopters. This AD requires inspecting the dome fairing support for a crack at the dome fairing attachment point. If a crack is found, this AD requires replacing the dome fairing support and the associated coning stop support assembly before further flight. If no crack is found, this AD requires repetitive inspections and retorquing the screws at specified intervals. This AD is prompted by the discovery of two fatigue cracks in the dome fairing attachment on the dome fairing support. This condition, if not corrected, could lead to the loss of the dome fairing in flight, causing damage to the helicopter and injury to people on the ground.
Special Conditions: Gulfstream Aerospace LP (GALP) Model G280 Airplane, Operation Without Normal Electrical Power
Document Number: 2011-27765
Type: Proposed Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
This action proposes special conditions for the Gulfstream Aerospace LP (GALP) Model G280 airplane. This airplane will have a novel or unusual design feature associated with operation without normal electrical power. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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; Agusta S.p.A. Model AB139 and AW139 Helicopters
Document Number: 2011-27690
Type: Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
This amendment supersedes an existing airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters. This action retains the requirements in the existing AD and adds a daily check of the tailboom panels to detect bulging or deformation of the tailboom outer skin panels. If there is bulging or deformation, this AD requires a mechanic to do a tap inspection for debonding. If the debonded area exceeds a certain limit, this AD requires modifying the tailboom. Also, when an area of debond does not exceed the limits, this AD requires, before further flight, repairing the debonded area of the tailboom or replacing the tailboom. This action also adds a tap inspection for additional tailboom panels and requires the inspection on both sides of the tailboom. This amendment is prompted by the determination that more inspections are required and to limit the applicability only to those helicopters with tailboom assemblies that have not been modified. Modifying the tailboom assembly is terminating action for the requirements of this AD. The actions specified in this AD are intended to detect damage in the tailboom to prevent failure of a tailboom and subsequent loss of control of a helicopter.
Airworthiness Directives; Bell Helicopter Textron Canada (Bell) Model 407 and 427 Helicopters
Document Number: 2011-27687
Type: Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2011-15-51, which was sent previously to all known U.S. owners and operators of the specified Bell Model 407 and 427 helicopters by individual letters. This AD requires inspecting certain hydraulic servo actuators to determine whether the shaft turns independently of the nut or the clevis assembly. If the shaft turns independently, this AD requires replacing the servo with an airworthy servo. If the shaft does not turn independently, the AD requires inspecting to determine the condition of the lock washers. Based on the condition of the lock washers, the AD requires either replacing the servo with an airworthy servo, or if any tab of the lock washer is not flush against a flat surface of the nut or clevis assembly, bending it flush against a flat surface. The AD also requires reidentifying the servo by metal-impression stamping or by vibro- etching ``67.01'' onto the modification plate. Also, the AD requires before installing a servo with a part number or serial number identified in this AD, not identified by ``67-01'' on the modification plate, inspecting it by following the requirements of this AD. This AD is prompted by a report that a quality escape by a supplier has occurred and certain servos may have a loose nut, shaft, and clevis assembly due to improper lock-washer installation. An investigation after an accident revealed the clevis nut on the servo was loose. The actions specified by this AD are intended to prevent a malfunction of a servo in the flight control system and subsequent loss of control of the helicopter.
Airworthiness Directives; Eurocopter France (Eurocopter) Model EC225LP Helicopters
Document Number: 2011-27680
Type: Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts a new airworthiness directive (AD) for the Eurocopter Model EC225LP helicopters. This AD requires inspecting the side mount of the pilot and copilot seats to determine if any floor attachment screw, nut, or washer is missing. If a screw, nut, or washer is missing, this AD also requires installing airworthy parts. This AD is prompted by a report that some of the floor attachment screws and nuts under the pilot and co-pilot seats were missing. Further investigation has shown that some of the cup washers that need to be used in installing countersunk head screws that attach the pilot and co-pilot seat frame to the floor were missing. A missing floor attachment screw, washer, or nut, if not detected, could reduce the strength of the seat attachment. The actions specified in this AD are intended to detect a missing floor attachment screw, washer, or nut and help prevent detachment of the seat from the floor during an emergency landing.
Airworthiness Directives; Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, and AS332L2 Helicopters
Document Number: 2011-27673
Type: Rule
Date: 2011-10-27
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter model helicopters. This action requires inspecting the upper end fitting ball joints of the main rotor servocontrols for lateral play, and depending on the findings either repetitively inspecting the ball joint or replacing the servocontrol. This amendment is prompted by reports of noncompliant swaging of the end fitting ball joints on main rotor servocontrols. Investigation has shown that the swaging load applied to the ball joints was 1.3 metric tons instead of the specified 13 metric tons. The actions specified in this AD are intended to prevent failure of the upper end fitting ball joints of the main rotor servocontrols, failure of the upper end fittings, and loss of control of the helicopter.
