Airworthiness Directives; Bombardier CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-2D24 (Regional Jet Series 900). Final rule. SUMMARY: 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: There have been several in-service cases reported of impact damage to the blowout (decompression) panel protective cage assemblies installed in the aft baggage cargo compartment. When damaged, these cages could prevent proper operation of the blowout panels, with potential degradation of smoke detection and fire extinguishing capabilities in the event of a fire. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective March 30, 2010.

Airworthiness Directives; EMBRAER ERJ 190-100 LR, -100 IGW, -100 STD, -200 STD, -200 LR, and -200 IGW. Final rule. SUMMARY: 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: During routine inspection procedures on the wing assembly line it was identified the possibility of cracks and deformation developing during assembly on the internal wing spars and rib flanges, causing a safety margin reduction. The unsafe condition is cracking and deformation of wing spar and rib flanges, which could result in loss of structural integrity of the wing. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective March 30, 2010.

Airworthiness Directives; Airbus A330-200 and A340-200 and -300. Final rule. SUMMARY: 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: [European Aviation Safety Agency (EASA)] AD 2006-0191 [which corresponds to FAA AD 2006-21-08] required the installation of new heat shield panels with drainage over the air conditioning packs in order to avoid an undetected fire in this zone following a fuel leak from the centre tank. These new heat shield panels have holes. In case of fuel leaking through these holes from the centre tank, any fuel vapour may develop into a potential source of ignition, possibly resulting in a fuel tank explosion and consequent loss of the aeroplane. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective March 30, 2010.

Airworthiness Directives; Airbus A310-203, -221, -222; and A300 F4-605R and -622R. Final rule. SUMMARY: 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: An A300-600 operator reported two events of IPECO pilot seat moved in the aft position, one during take-off roll and one during climb out. The investigation of these events showed that a broken/missing spring contributed to the seat not being correctly locked. An unwanted movement of pilot or co-pilot seat in the aft direction is considered as potentially dangerous, especially during the take-off phase when the speed of the aeroplane is greater than 100 knots and until landing gear retraction. The unsafe condition is potential loss of control of the airplane during take-off and landing. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective March 30, 2010.

Airworthiness Directives; ATR42 and ATR72. Final rule; request for comments. SUMMARY: 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: The Civil Aviation Authority of the United Kingdom (UK) has informed EASA [European Aviation Safety Agency] that significant quantities of Halon 1211 gas, determined to be outside the required specification, have been supplied to the aviation industry for use in fire extinguishing equipment. This Halon 1211 has subsequently been used to fill certain portable fire extinguishers that are now likely to be installed in or carried on board ATR aeroplanes. The contaminated nature of this gas, when used against a fire, may provide reduced fire suppression, endangering the safety of the aeroplane and its occupants. In addition, extinguisher activation may lead to the release of toxic fumes, possibly causing injury to aeroplane occupants. This AD requires actions that are intended to address the unsafe condition described in the MCAI. DATES: This AD becomes effective March 12, 2010.
