Piaggio Aero Industries S.p.A. Model P-180 Airplanes
This document supersedes Airworthiness Directive (AD) 2003-03- 14, which applies to all PIAGGIO AERO INDUSTRIES S.p.A. (PIAGGIO) Model P-180 airplanes. AD 2003-03-14 currently requires you to inspect and determine whether any firewall shutoff or crossfeed valve with a serial number in a certain range is installed and requires you to replace or modify any valve that has a serial number within this range. The modification consisted of reworked valves that were re-identified with an "A" at the end of the serial number. AD 2003-03-14 allows the pilot to check the logbook and does not require the inspection and replacement requirement if the check shows that one of these valves is definitely not installed. Since AD 2003-03-14 became effective, the Federal Aviation Administration (FAA) has found that the valve manufacturer was not correctly incorporating the modification on reworked valves. Consequently, the installation of modified fuel valves installed per AD 2003-03-14 could allow the unsafe condition to remain on the affected airplanes. This AD would require you to replace any firewall shutoff or crossfeed valve with a serial number in a certain range even if it has been modified per AD 2003-03-14. The actions specified by this AD are intended to prevent a faulty firewall shutoff or crossfeed valve from developing cracks and leaking fuel. This could result in an engine fire.

(RR) models RB211-535E4-37, RB211- 535E4-B-37, and RB211-535E4-B-75 turbofan engines, with certain part number (P/N) low pressure (LP) turbine stage 2 discs installed. That AD currently requires establishing new reduced LP turbine stage 2 disc cyclic limits. That AD also requires removing from service affected discs that already exceed the new reduced cyclic limits, and removing other affected discs before exceeding their cyclic limits, using a drawdown schedule. This amendment requires changing certain cyclic limits, changing the effective date of certain disc cyclic lives, and would allow intermix of Flight Plan A and Flight Plan B intermix calculations. This amendment is prompted by a reassessment of the thermal and stress data from recent operational experience and comments received from operators on the current AD. We are issuing this AD to prevent LP turbine stage 2 disc failure, which could result in uncontained engine failure and possible loss of the airplane.

McCauley Propeller Systems, Inc. Propeller Hub Models B5JFR36C1101, C5JFR36C1102, B5JFR36C1103, and C5JFR36C1104
The FAA is superseding an existing airworthiness directive (AD) for McCauley Systems, Inc. propellers that are installed on, but not limited to, BAE Systems (Operations) Limited Jetstream Model 4101 airplanes. That AD currently requires a one-time fluorescent penetrant inspection (FPI) of propeller blade retention areas for cracks. This AD requires initial and repetitive FPI or Ultrasonic Inspection (UT) of propeller blade retention areas for cracks, replacement of high time propeller blades, and a one-time inspection of propeller hubs. This AD is prompted by four reports of significant cracks found in propeller blade shanks since the issuance of AD 2003-15-01. We are issuing this AD to prevent propeller blade failure or hub failure due to cracking, which could result in failure of the propeller and loss of control of the airplane.

Schempp-Hirth Flugzeugbau GmbH Gliders
This amendment adopts a new airworthiness directive (AD) that applies to certain Schempp-Hirth (SCHEMPP-HIRTH) Flugzeugbau GmbH Model Duo-Discus gliders. This AD requires you to accomplish a one-time inspection of the bonding of the spar cap and spar web, and repair any defective bonding of the spar cap and spar web. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to detect and correct failure of the bonding of the spar cap and spar web, which if not detected and corrected, could result in an in-flight failure of the wing.

Various Transport Category Airplanes Manufactured by McDonnell Douglas
This amendment adopts a new airworthiness directive (AD), applicable to various transport category airplanes manufactured by McDonnell Douglas. This AD requires a one-time test of the fire extinguishers for the engine and auxiliary power unit (APU), as applicable, to determine the capability of the Firex electrical circuits to fire discharge cartridges, and troubleshooting actions if necessary. This action is necessary to prevent failure of the fire extinguishers to fire discharge cartridges, which could result in the inability to put out a fire in an engine or in the APU. This action is intended to address the identified unsafe condition.
