Plain English Summary

3/10 complexity

This Airworthiness Directive requires owners/operators of Beechcraft Bonanza A36TC aeroplanes (serials EA-1–EA-146) to fit a higher‑temperature drain hose to the engine fuel metering unit and to carry out modification and inspection work described in Beechcraft Mandatory Service Bulletin No. 2420 Rev.1. The measure is intended to reduce the risk of a fuel leak and possible engine‑compartment fire. CASA enforces the AD; operators pay for parts and labour, must schedule the work and adopt repetitive drain‑hose inspections into ongoing maintenance.

Background: This directive was originally issued in March 1993 to require the inspection and modification of the engine fuel metering unit. The requirement was published to reduce the possibility of a fuel leak which could result in an engine compartment fire. This amendment introduces a requirement to fit a fuel metering unit drain hose with a higher temperature tolerance material, and a requirement to carry out a repetitive inspection of that drain hose.

The original issue of this Airworthiness Directive became effective on 4 March 1993.
