AD on Honeywell Navigation affecting Bell Helicopter and Agusta, Cessna, Dassault, Embraer, Gulfstream and Lear in the GA arena, Airbus and Boeing in the Large Aircraft or Commercial Sector

Thursday, January 10th, 2013

The FAA is adopting a new airworthiness directive (AD) 2012-26-15 for certain Honeywell International Inc. air data pressure transducers as installed on various aircraft. This AD requires various tests or checks of equipment having certain air data pressure transducers, and removal of equipment if necessary. As an option to the tests or checks, this AD allows removal of affected equipment having certain air data pressure transducers. This AD was prompted by a report of a pressure measurement error in the pressure transducer used in various air data systems, which translates into air data parameter errors. We are issuing this AD to detect and correct inaccuracies of the pressure sensors, which could result in altitude, computed airspeed, true airspeed, and Mach computation errors. These errors could reduce the ability of the flightcrew to maintain the safe flight of the aircraft and could result in consequent loss of control of the aircraft.

DATES: This AD is effective January 24, 2013.

An unsafe condition exists that requires the immediate adoption of this AD 2012-26-15. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because inaccuracies of the pressure sensors could result in altitude, computed airspeed, true airspeed, and Mach computation errors. These errors could reduce the ability of the flightcrew to maintain the safe flight of the aircraft and could result in consequent loss of control of the aircraft. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days.

The FAA estimates that this AD affects 90 appliances installed on, but not limited to, various aircraft of U.S. registry.

The manufacturer is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, the FAA said they might consider additional rulemaking.

Emergency AD for Cracked fitting on Bell Helicopters

EMERGENCY AIRWORTHINESS DIRECTIVE 2010-24-52 – Bell Helicopter

This EAD supersedes EAD 2010-24-51, dated November 12, 2010 (EAD 2010-24-51), and is prompted by the need to expand the applicability of the existing EAD to include the serial-numbered main rotor hub inboard strap fittings (fittings) from an additional manufacturing lot.

Bell states they have determined that the fitting may not have been manufactured in accordance with the engineering design requirements and may fracture as a result of the non-conformance. Bell further states that their investigation is ongoing, and indicates that the ASB affects the fitting, part number 212-010-103-007, S/Ns as listed in Table 1 below:

Table 1 Affected S/Ns
A-9956 through A-10005
SH-52, SH-54, SH-55
SH-57 through SH-65
SH-67, SH-69, SH-70, SH-71, SH-73
SH-103, SH-112, SH-113, SH-137, SH-139

Bell Helicopter Model 429 Clam Shell Doors

Monday, August 9th, 2010

Below is excerpt…click here for more.

SAIB No. SW-10-15 was issued February 5, 2010 to owners, operators, and modifiers of the Bell Model 429 helicopter to advise them that any modification to incorporate the clam shell doors as passenger exits would need additional FAA evaluation and approval as the clam shell doors at initial type certification were not approved as passenger exits but were approved as baggage access doors only.

Since that time, Bell Helicopter has successfully demonstrated that this baggage area access can be used for loading and unloading of cargo or occupants safely.
