Rudder Airworthiness Directive (AD) 2004-14-14
We have received confirmation from the FAA that aircraft that have previously been inspected inaccordance with Section 5-40-03 (dated January 31, 2003) of the structural inspection program (structural“B”) meet the requirements of paragraph (a).We are discussing an adjustment to the AD compliance time of 50 hours with the FAA. It seems that theFAA, Civil Aviation Administration of Israel (CAAI), and Israel Aircraft Industries (IAI) weren’t in agreementas far as the compliance times were concerned. Unfortunately, your local Flight Standards District Office(FSDO) is not authorized to grant an extension to the 50-hour limit. That must be done through the FAA inSeattle using the Alternate Means of Compliance (AMOC) procedure. Contact Dan Rodina at 425-227-2125.He is the FAA person whose name is at the bottom of the AD.

Emergency Battery Maintenance
The Emergency Gyro and Emergency Lighting Batteries are an important part of your Westwind’s operating systems. Chapter 5-25-00 of the 1124 / 1124A Westwind Maintenance Manual requires the batteries to be checked every 200 hours or 3 months. Many people consider this requirement to be a nuisance. Quite often we find the batteries have been run down or their inspection interval was ignored. Don’t let this happen to you. Take the time to check your batteries. Try putting them in sync with your “A”Inspection if possible. If you are tracking them by calendar time, be sure to give yourself enough turn time, as they require 16 hours to charge. Considering their importance in the event you should need them, you will be glad you took the time to ensure their airworthiness.

Engine ITT Indicating
Scenario:
During a routine engine run/leak check following a scheduled inspection, the technician has started the number 2 engine first and keeps engine speed remaining at idle while the leak checks are performed. The right engine nacelle anti-ice valve has mechanically failed open, and HP bleed air is flowing to the right engine nacelle.
Answer:
There will be no cockpit indication except for higher Interstage Turbine Temperature (ITT); with one engine running, there is nothing to compare to. Since the switch is in the OFF position, no cockpit annunciators on the switch will be illuminated. To check for proper operation, the technician should turn the anti-ice ON after start and look for a rise in ITT and the ON and ENG light illuminated on the switch. Once verified, turn the switch OFF, and the lights should extinguish and ITT should return to normal.
