AAIB Launches Urgent Inquiry After London Heathrow Near Miss Incident

The Air Accidents Investigation Branch (AAIB) has launched a formal probe. This follows a serious incident at London Heathrow Airport (LHR). The event involved two commercial passenger aircraft. They experienced a loss of separation incident near the runway. The AAIB is the UK’s official body for investigating aviation accidents. This inquiry aims to determine the exact circumstances and causes.

Investigation Focus

The core of the investigation is the Air traffic control investigation. Air traffic controllers (ATC) are reviewing all procedures. The focus is on communication and coordination protocols. The incident occurred during a high-workload phase of flight. This phase is typically either approach or departure. Previous incidents have highlighted communication breakdowns. These often occur between controllers managing different sectors. The AAIB will analyze ATC recordings and radar data. They will also review the actions of the controllers involved.

Safety Systems Review

Investigators are also looking at the aircraft systems. They are checking if the Traffic Alert and Collision Avoidance System (TCAS avoidance system) was triggered. TCAS is a crucial safety layer. It alerts pilots to conflicting traffic. It then directs them to take corrective action. The pilots of at least one aircraft may have initiated a go-around procedure. This is a standard maneuver to abort a landing. It is used when a runway is occupied or separation is lost.

Commercial Aviation Safety and Oversight

Near-miss events are formally classified as Airprox occurrences in the UK. The UK Airprox Board (UKAB) typically investigates these. However, the AAIB takes control for serious incident classification. This signals the high potential risk involved. The UK Air Accidents Investigation Branch (AAIB) reports to the Department for Transport. Their findings are critical for improving commercial aviation safety.

Regulatory and Industry Impact

LHR runway safety is paramount due to its high traffic volume. Heathrow is one of the world's busiest airports. The UK Air traffic management (ATM) system handles millions of flights safely each year. Such incidents, while rare, erode the margin for error. The final AAIB report will likely issue safety recommendations. These recommendations will target procedural changes for ATC provider NATS. They may also affect training and technology. The UK Civil Aviation Authority (CAA) oversees the implementation of these safety actions.

Aviation safety protocols rely on multiple redundancies. This includes both human performance and technological safeguards. The outcome of this inquiry will inform future global best practices. The industry must maintain constant vigilance. This is the price of safety in a complex air traffic environment.
