What to do
Operators of affected Boeing 767-300 aircraft must complete the implementation of IAI Service Bulletin 368-34-106 within 36 months from August 6, 2024. Maintenance teams should inspect and correct the routing of the specified flexible hoses and rigid tubes to eliminate water traps in the pitot-static system. Contact the Civil Aviation Authority of Israel for further technical guidance if needed.
Summary
Airworthiness Directive ISR I-34-2024-07-1 issued by the Civil Aviation Authority of Israel addresses improper rerouting of pitot-static tubing after conversion of Boeing 767-300 aircraft from passenger to freighter configuration. This directive applies to aircraft with the CAAI STC SA-218 modification installed, affecting the pitot and static system tubing connected to the first officer's Air Data Computer. The issue involves potential water traps in specific flexible hoses and rigid tubes that may impair system functionality.
What changed
This new Airworthiness Directive introduces mandatory compliance with Israel Aerospace Industries Service Bulletin 368-34-106 to correct the improper rerouting of pitot-static tubing after structural reinforcements during aircraft conversion. It identifies specific part numbers of flexible hoses and rigid tubes that create water traps and mandates their proper installation to prevent system malfunction.
Why it matters
The directive is critical for aviation professionals because improper pitot-static tubing routing can lead to water accumulation, causing erroneous air data readings and potential failure of the first officer's Air Data Computer. Operators and maintenance organizations must address this to ensure flight safety and regulatory compliance, avoiding operational disruptions or safety incidents.
