Airworthiness Directives; Eurocopter France Model SA-365C, SA-365C1, SA-365C2, SA-365N, SA-365N1, AS-365N2, AS 365 N3, and SA-366G1 Helicopters
Document Number: 2011-14248
Type: Rule
Date: 2011-06-17
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) helicopters. This action requires visually inspecting the adhesive bead between the bushing and the Starflex star (Starflex) arm for a crack, a gap, or loss of the adhesive bead, inspecting the Starflex arm ends for delamination, and replacing the Starflex if any of these conditions are found. This amendment is prompted by three cases of deterioration of a Starflex arm. In two of these cases, the deterioration caused high amplitude vibrations in flight, compelling the pilot to make a precautionary landing. The actions specified in this AD are intended to prevent failure of the Starflex, high-amplitude vibrations in flight, and subsequent loss of control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron, Inc. Model 205A, 205A-1, 205B, 212, 412, 412CF, and 412EP Helicopters
Document Number: 2011-14247
Type: Rule
Date: 2011-06-17
Agency: Federal Aviation Administration, Department of Transportation
This amendment adopts a new airworthiness directive (AD) for the specified Bell Helicopter Textron, Inc. (BHT) model helicopters with tail rotor (T[sol]R) blades with certain serial numbers installed. This action requires a one-time inspection of the T[sol]R blade for corrosion or pitting, and repairing or replacing the T[sol]R blade, if that condition is found during the inspection. This amendment is prompted by a report from the manufacturer that T[sol]R blades with certain serial numbers may have manufacturing anomalies in the spar area. These actions are intended to detect corrosion or pitting in the forward spar area of a T[sol]R blade to prevent a crack in the T[sol]R blade, loss of the T[sol]R blade, and subsequent loss of control of the helicopter.
Airworthiness Directives; Robinson Helicopter Company Model (Robinson) R22, R22 Alpha, R22 Beta, R22 Mariner, R44, and R44 II Helicopters
Document Number: 2011-14246
Type: Rule
Date: 2011-06-17
Agency: Federal Aviation Administration, Department of Transportation
This amendment supersedes an existing airworthiness directive (AD) for the specified Robinson model helicopters that currently requires a visual inspection for skin separation along the leading edge of blade skin aft of the skin-to-spar bond line on the lower surface of each main rotor blade (blade) and in the tip cap area. The existing AD also requires a ``tap test'' for detecting a separation or void in both bonded areas and repainting any exposed area of the blades. If any separation or void is detected, the AD requires, before further flight, replacing the blade. Thereafter, before each flight, the existing AD also requires checking for any exposed (bare) metal along the skin-to- spar bond line on the lower surface of each blade near the tip. If any bare metal is found, that AD requires an inspection by a qualified mechanic. This amendment contains the same requirements but expands the applicability to include all serial-numbered model helicopters and limits the applicability to specific blade part numbers. This amendment also requires a repetitive inspection of the blade and any necessary rework. This amendment is prompted by a fatal accident in Israel. We have also included responses to comments objecting to the recording requirements in the current AD relating to the pilot checks before each flight and to comments that the burden of the before-each-flight pilot check exceeds the benefit. We have concluded that a check before the first flight of each day is sufficient for aviation safety. The actions specified by this AD are intended to provide more specific AD actions, to relieve the burdens associated with the before-each-flight check by changing it to a daily check, to detect blade skin debond, and to prevent blade failure and subsequent loss of control of the helicopter.

Medical Certification Requirements as Part of the Commercial Driver's License (CDL); Extension of Certificate Retention Requirements
Document Number: 2011-14653
Type: Proposed Rule
Date: 2011-06-14
Agency: Federal Motor Carrier Safety Administration, Department of Transportation
The FMCSA proposes to keep in effect until January 30, 2014, the requirement that interstate drivers subject to the commercial driver's license (CDL) regulations and the Federal physical qualification requirements must retain a paper copy of the medical examiner's certificate. Interstate motor carriers would also be required to retain a copy of the medical certificate in the driver qualification files. This action is being taken to ensure the medical qualification of CDL holders until all States are able to post the medical self-certification and medical examiner's certificate data on the Commercial Driver's License Information System (CDLIS) driver record. This proposed rule would not, however, extend the mandatory dates for States to comply with the requirement to collect and to post to the CDLIS driver record data from a CDL holder's medical self- certification and medical examiner's certificate.

Airworthiness Directives; Airbus Model A330-200 and -300 Series Airplanes, and Model A340-200 and -300 Series Airplanes
Document Number: 2011-14398
Type: Rule
Date: 2011-06-10
Agency: Federal Aviation Administration, Department of Transportation
This amendment rescinds airworthiness directive (AD) 2009-18- 19 for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by EASA, to rescind EASA AD 2010-0083. The MCAI specifies the following:
Airworthiness Directives; Bombardier, Inc. Model CL-215-1A10, CL-215-6B11 (CL-215T Variant), and CL-215-6B11 (CL-415 Variant) Airplanes
Document Number: 2011-14397
Type: Proposed Rule
Date: 2011-06-10
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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; Viking Air Limited (Type Certificate No. A-815 Formerly Held by Bombardier Inc. and de Havilland, Inc.) Model DHC-3 Airplanes
Document Number: 2011-14396
Type: Proposed Rule
Date: 2011-06-10
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede an existing airworthiness directive (AD) that applies to the products listed above. The existing AD currently requires repetitively inspecting the elevator control tabs for discrepancies and, if any discrepancies are found, taking necessary corrective actions to bring all discrepancies within acceptable tolerances. The existing AD also requires reporting certain inspection results to the FAA. Since we issued that AD, we determined that we inadvertently omitted certain airplanes from the Applicability section. This proposed AD would retain the actions currently required in AD 2011-05-02 and remove the Supplemental Type Certificate (STC) SA01059SE condition in the Applicability section. We are proposing this AD to add new repetitive inspections of the elevator control tabs. If these inspections are not done, excessive free-play in the elevator control tabs could develop. This condition could lead to loss of tab control linkage and severe elevator flutter. Such elevator flutter could lead to possible loss of control.
