We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires an inspection to determine if a certain fuel pump housing electrical connector is installed. The existing AD also requires a revision to the FAA-approved airplane flight manual (AFM) to advise the flightcrew of the appropriate procedures for disabling certain fuel pump electrical circuits following failure of a fuel pump housing electrical connector if applicable. The existing AD also requires the deactivation of certain fuel tanks or fuel pumps and the installation of placards if applicable. The existing AD allows the optional replacement of the fuel pump housing electrical connectors with new, improved parts, which would terminate the AFM revisions, deactivation of certain fuel tanks and fuel pumps, and placard installation. This new AD instead requires replacing the fuel pump housing electrical connector assembly with a new part and doing repetitive inspections for continuity, resistance, and insulation resistance, and doing corrective actions if necessary. This AD was prompted by reports of failures of a certain fuel pump housing electrical connector. We are issuing this AD to detect and correct insulation resistance degradation and arcing in the potted backside of the electrical connector assembly of the fuel boost/ transfer pump housing, which could compromise its performance and cause an ignition source in the fuel tank, resulting in a fuel tank explosion and consequent loss of the airplane.

Piaggio Aero Industries S.p.A. Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. This emergency AD was sent previously to all known U.S. owners and operators of PIAGGIO AERO INDUSTRIES S.p.A (Piaggio) Model PIAGGIO P-180 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: Prompted by reports of water accumulated in the lower part of the fuselage on a number of Piaggio Model P.180 aeroplanes, which resulted in jamming of the flight controls, on 17 December 2010, the Federal Aviation Administration (FAA), the authority of the State of Registry of the affected aeroplanes, issued Emergency AD 2011-01-51 to require an immediate functional test of the fuselage drain holes and a report of the results to the FAA. That AD was later superseded, on 20December 2010, by FAA Emergency AD 2011-01-53. This condition, if not detected and corrected, could, when the aeroplane reaches and holds an altitude where the temperature is below the freezing point, cause the flight controls to freeze and jam, possibly resulting in loss of control of the aeroplane. Since these AD actions were taken, Piaggio Aero Industries, the type design approval holder and manufacturer of these aeroplanes, have published Alert Service Bulletin (SB) 80-0324, which describes the same inspection, testing and correction instructions as contained in the FAA Emergency AD. EASA AD 2010-0269-E required the inspection and functional testing of the fuselage drain holes, corrective actions depending on findings, and reporting of the findings to Piaggio Aero Industries. Following issuance of EASA AD, another event of in-flight blockage of flight controls was reported by an operator. The aeroplane was already compliant with EASA AD 2010-0269-E, and during accomplishment of the AD required inspection no discrepancies had been noted, nor water or ice accumulation were reported. As a consequence, additional drain holes were not drilled. This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Robinson Helicopter Company Model (Robinson) R22, R22 Alpha, R22 Beta, R22 Mariner, R44, and R44 II Helicopters
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.
