Erroneous information may also place an excessive workload on the flightcrew while they monitor other available navigation data to avoid deviating off course. This action is intended to address the identified unsafe condition.

Boeing Defense and Space Group Model 234 Helicopters
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2004-06-51, which was sent previously to all known U.S. owners and operators of Boeing Defense and Space Group (Boeing) Model 234 helicopters by individual letters. This AD requires, before further flight, inspecting the upper shaft extension for a crack and modifying the aft vertical shaft assembly (assembly). Thereafter, this AD requires, before the first flight of each day, inspecting the upper shaft extension for any crack. If any crack is found during any of the inspections, replacing the assembly with an airworthy assembly is required before further flight. This amendment is prompted by the discovery of a crack in the upper shaft extension of an assembly. The actions specified by this AD are intended to detect a crack in the upper shaft extension, which could result in catastrophic failure of the assembly and subsequent loss of control of the helicopter.

Eurocopter France Model EC 130 B4 and AS 350 B3 Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters that requires inspecting the fuel transfer line and air exhaust duct for chafing, inspecting the air exhaust duct for a hole, and if necessary, repositioning the air exhaust duct to achieve the minimum clearances. This amendment is prompted by a report of damage to the fuel transfer line due to wear associated with vibrations and chafing of the fuel transfer line and the air exhaust duct. The actions specified by this AD are intended to detect chafing wear of the air exhaust duct and the fuel transfer line, which could result in a hole in the fuel transfer line, fuel leaking into the engine compartment and creating a fire hazard that could lead to a fire and a subsequent forced landing.

This amendment adopts a new airworthiness directive (AD) for the specified Agusta S.p.A. (Agusta) model helicopters that requires disabling certain windshield wipers and thereafter modifying the electrical system of the windshield wipers by installing a new resistor and condenser, eliminating incompatibility problems with the relays, and replacing the timed relay for certain windshield wiper kits. This amendment is prompted by testing that revealed overheating of the electrical resistor on the electrical system of the windshield wipers due to a system overload because of a partial incompatibility of new timed relays with the configuration of the windshield wiper electrical system. The actions specified by this AD are intended to prevent the incompatibility of certain relays with the windshield wiper electrical system, overheating of the resistor due to system overload, and an electrical fire.

Eurocopter France Model EC 155 B and B1 Helicopters
This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC 155 B and B1 helicopters. This action requires inspecting each main rotor blade (blade) for a crack in the blade tip cap mounting bracket (tenon), measuring the vertical clearance between each blade assembly and a straight edge at the blade-to-tip cap junction, and replacing the blade if a crack is found or if the measured distance is not within certain specifications. This amendment is prompted by the discovery of a crack in a tenon. This condition, if not detected, could result in loss of the tip cap, which could lead to severe vibration and loss of control of the helicopter.

Agusta S.p.A. Model A109C, A109E, and A109K2 Helicopters
This amendment revises an existing airworthiness directive (AD), for the Agusta S.p.A. (Agusta) Model A109C, A109E, and A109K2 helicopters, that currently requires inspecting the main rotor blade (blade) tip cap for bonding separation and a crack, and also requires a tap inspection of the tip cap for bonding separation in the blade bond area and a dye-penetrant inspection of the tip cap leading edge along the welded joint line of the upper and lower tip cap skin shells for a crack. This amendment requires those same actions, but corrects a blade part number (P/N) that was stated incorrectly in the Applicability section of the existing AD. This amendment is prompted by the need to correct a blade P/N. The actions specified by this AD are intended to prevent failure of a blade tip cap, excessive vibration, and subsequent loss of control of the helicopter.

Rolls-Royce (1971) Limited, Bristol Engine Division Model Viper Mk.601-22 Turbojet Engine
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce (1971) Limited, Bristol Engine Division (RR) Model Viper Mk.601-22 turbojet engines. This AD requires reducing the life of certain 1st stage turbine rotor blades from 7,000 hours time-in-service (TIS) to 4,600 hours TIS, and provides a drawdown schedule for blades that have already exceeded the new reduced life limit. This AD results from the manufacturer's investigations into failures of 1st stage turbine rotor blades. We are issuing this AD to prevent multiple failures of 1st stage turbine rotor blades that could result in a dual- engine shutdown.

This AD requires initial and repetitive visual inspections or ultrasonic inspections of the intermediate pressure (IP) compressor rear stubshaft and IP turbine shaft for load-bearing spline flank wear, and replacement of these shafts if necessary. This AD results from reports of load-bearing spline flank wear of the IP compressor rear stubshaft and IP turbine shaft, revealed at inspection during overhaul. We are issuing this AD to prevent the loss of drive between the IP turbine and the IP compressor, which could result in a turbine rotor overspeed condition, possible uncontained engine failure, and damage to the airplane.

Hamilton Sundstrand Corporation (Formerly Hamilton Standard Division) Model 568F Propellers
The FAA is adopting a new airworthiness directive (AD) for certain serial-numbered propeller blades installed in Hamilton Sundstrand Corporation (formerly Hamilton Standard Division) 568F propellers. This AD requires replacement of propeller blades, part numbers (P/Ns) R815505-3 and R815505-4 that have a serial number (SN) of FR1699 to FR20021010, with serviceable blades. This AD results from reports of these composite propeller blades found at inspection, with random areas of missing adhesive under the compression wrap, which exposed the steel tulip part of the blade. We are issuing this AD to prevent propeller blade failure due to corrosion-induced fatigue, which could result in blade separation and possible loss of airplane control.
