Overview
On December 8, 2024, a DHL Aero Expreso Boeing 767-300 freighter (registration HP-3310DAE) performing flight D5-926 from Bogota, Colombia, to Miami, Florida, USA, rejected takeoff at high speed on Bogota’s runway 14R. The rejection was due to a “L ENG PRV” (left engine pressure regulation valve) indication received at approximately 140 knots indicated airspeed (KIAS). The aircraft safely vacated the runway but became disabled on taxiway K6 due to deflation of seven tyres on both the left and right main landing gear.
Key Details
• Aircraft Registration: HP-3310DAE
• Flight Number: D5-926
• Route: Bogota (SKBO) to Miami (KMIA)
• Incident Date: December 8, 2024
• Cause: “L ENG PRV” indication prompting rejected takeoff
• Outcome: No injuries, seven tyres deflated, aircraft disabled on taxiway
Sequence of Events
1. Takeoff Roll:
• The aircraft was accelerating for takeoff on runway 14R at Bogota when the crew received a “L ENG PRV” warning at approximately 140 KIAS.
2. Rejected Takeoff:
• The takeoff was aborted at around 160 knots over ground.
• The aircraft safely decelerated and vacated the runway onto taxiway K6.
3. Aircraft Disabled:
• Due to the rejected takeoff at high speed, seven tyres on the left and right main landing gear deflated, rendering the aircraft immobile.
• Cargo was unloaded directly onto the taxiway to facilitate recovery operations.
4. Replacement Flight:
• A replacement Boeing 767-300 freighter (registration HP-3610DAE) was dispatched to carry the cargo to Miami, arriving approximately 11 hours later.
Preliminary Investigation Findings
• Indication: The crew received a “L ENG PRV” warning indicating a fault with the left engine pressure regulation valve (GE CF6 engine).
• Tyre Deflation: The high-speed rejection caused excessive heat buildup, leading to thermal fuse plugs melting and deflating seven tyres across both main landing gear assemblies.
• Aircraft Status:
• The disabled aircraft was towed after cargo unloading.
• The aircraft was returned to service on December 12, 2024.
Impact
1. Operational Delays:
• The cargo shipment was delayed by approximately 11 hours due to the need for a replacement aircraft.
2. Aircraft Damage:
• Extensive tyre deflation required repairs before the aircraft could return to service.
Recommendations
1. Engine Monitoring:
• Enhanced inspection and monitoring of pressure regulation valves to detect potential issues before takeoff.
2. High-Speed RTO Protocols:
• Evaluate procedures to minimize tyre damage during rejected takeoffs at high speeds.
3. Runway Safety:
• Ensure efficient coordination for runway clearance and recovery operations in case of aircraft immobility.
Conclusion
The quick decision by the crew to reject takeoff ensured a safe outcome for the aircraft and crew. However, the incident underscores the importance of thorough preflight checks, particularly for systems critical to high-performance takeoffs. The ongoing investigation by Colombia’s DIACC aims to provide further insights and safety recommendations.
