ELT Wiring
If you are approaching an 800-hr. “C” inspection, plan on at least installing the wiring for the Emergency Locator Transmitter (ELT). This requirement becomes effective January 1, 2004. The new 406 MHz unit will be required in 2009, but it is twice as expensive as the old 121.5 MHz unit, which is still approved.

Brake & Hydraulic Indicating Fuse Checks
Westwind 1124/1124A maintenance technicians and operators are reminded of the recurring requirement to perform a functional test of the hydraulic fuses in their aircraft. Airworthiness Directive (AD) 98-06-10,Amendment 39-10387, states that a repetitive functional test of the hydraulic fuses in the brake system and emergency hydraulic indicating system will be done every 1,200 hours or 3 years after the initial inspection,which ever comes first, in accordance with Westwind Service Bulletin 1124-29-132.
This test is to make sure the fuse will stop the flow of hydraulic fluid after a leak has been detected. Some operators feel the AD no longer applies, if they had the brake fuse checked during brake change or if a fuse had been replaced. This is not so. There is no terminating action for the AD at this time. Both brake fuses and the indicating fuse need to be addressed in signing off the AD. Check your records to be sure you are in compliancewith this requirement.
