What to do
Operators of the Convair 580 should review and update their training programs to reinforce approved fuel cross-feed procedures. They must ensure that fuel boost pumps are set to identical pressure settings on both tanks as recommended. Safety directors and pilots should familiarize themselves with the SAIB, related SAFO 06-011, and the NTSB accident report to ensure uniform compliance. No specific compliance deadline is stated.
Summary
FAA Special Airworthiness Information Bulletin (SAIB) NE-07-24 addresses safety concerns for the Kelowna Flightcraft R & D Ltd Model Allison Prop-Jet Convair 340/440, known as the Convair 580 aircraft. The bulletin emphasizes adherence to approved fuel cross-feed operating procedures and recommends using boost pumps with identical pressure settings on both sides to prevent fuel starvation incidents. This document is supported by EASA Safety Information Notice 2007-09, which reinforces these recommendations for operators within Europe.
What changed
This SAIB introduces a strong recommendation to operate the Convair 580 aircraft with identical fuel boost pump pressure settings on both tanks, despite previous allowances for differing pressures. It reiterates mandatory procedures for emergency fuel cross-feed operations as outlined in the Aircraft Flight Manual, including turning off the fuel valve and boost pump on the tank not in use. The bulletin also highlights the prohibition of fuel transfer between tanks to avoid structural damage or fuel overflow.
Why it matters
Adhering to these procedures is critical to prevent fuel starvation, which has previously led to a fatal accident involving the Convair 580. Operators, maintenance, and training personnel must ensure consistent understanding and application of fuel cross-feed protocols to maintain flight safety and regulatory compliance. Proper boost pump settings and procedural compliance reduce the risk of unintended fuel transfer and associated hazards.
