Nose Gear Collapse at Kaduna: Accident or Incident, and Who Is Told What
You are the pilot-in-command of 5N-BXG, a Cessna 208B Caravan on a domestic charter from Abuja (DNAA) to Kaduna (DNKA) with nine passengers and one cabin crew member. On landing at Kaduna the nose gear collapses, the propeller strikes the runway and the aircraft comes to rest on the centreline. The engine stops. There is no fire. One passenger injures a wrist on the seat in front while evacuating and is taken to hospital, where she is treated and released the same day. The aircraft has a destroyed propeller, damaged nose gear and distorted firewall, and the operator's maintenance organisation says it will require major repair. Airport rescue and fire fighting are in attendance. The operator's duty manager asks you to move the aircraft to the apron so the runway can reopen and to give a statement to the company's insurer before you speak to anyone else.
1. How is this occurrence classified under the accident investigation framework, and why does the classification matter?
Read the worked answer
It is an accident, and there are at least three independent grounds.
- Damage. The aircraft sustained damage or structural failure that adversely affects its structural strength, performance or flight characteristics and would normally require major repair or replacement of the affected component. A destroyed propeller, collapsed nose gear and distorted firewall plainly meet that test.
- Injury. A person was injured - although the 'accident' injury threshold is normally serious or fatal injury, an injury requiring hospital treatment should be assessed against the definition rather than assumed to be a mere incident.
- Position on the aerodrome. An occurrence between the time any person boards with intent to fly and the time all have disembarked is within the definition, so the runway location does not remove it from the framework.
Classification matters because it triggers a different legal regime: mandatory immediate notification, the investigation authority's primacy over the site and the wreckage, protection of recorded data, and specific reporting duties on the operator. Treating it as a routine ramp incident and moving the aircraft would itself be a breach. The correct instinct is to notify first and move nothing except for rescue, firefighting or to prevent further danger.
2. What are your immediate and follow-on obligations, in order, and what must you not do?
Read the worked answer
Immediately on the runway:
- Account for all persons; arrange medical care; ensure ARFF is in attendance, and do not allow anyone to smoke near fuel.
- Do not move the aircraft, except to save life or prevent fire.
- Preserve the site: prevent unauthorised access, do not disturb wreckage or switch positions, and do not allow anyone to reset or remove avionics.
- Protect recorded data: ensure the flight data and cockpit voice recordings, if fitted, are secured and not overwritten. Do not run the engine or power the aircraft in a way that erases data.
Notification:
- Notify the investigating authority for the State of Occurrence without delay - in Nigeria the Nigerian Safety Investigation Bureau - and the NCAA. Also notify the aerodrome operator and the operator's accountable manager.
- The operator files the mandatory occurrence report through its safety system.
Follow-on:
- Secure the technical log, journey log, licences, loadsheet and weather documents.
- Preserve maintenance and crew duty records for the flight.
- Cooperate fully with the investigators.
Do not: move the wreckage, give speculative statements to the media, discuss the occurrence on social media, or sign an insurer's statement that conflicts with your obligation to the investigating authority.
3. The chief pilot wants the cockpit voice recording and a company statement before you speak to the Bureau. How do you handle that?
Read the worked answer
Under the accident investigation framework, cockpit voice recordings and transcripts are protected: they are used for investigation purposes and are not released for disciplinary, civil or administrative purposes except where the State has legislated an exception and the recording is needed for the administration of justice. Deciding what happens to a recording is not the chief pilot's call, nor the insurer's; it belongs with the investigating authority. Your duty is to preserve and hand over custody, not to copy or distribute it.
On the statement: writing to your insurer is not unlawful, but it must not compromise the investigation. Ask the Bureau what it needs and when, and give the company a factual, non-speculative account consistent with what you will tell the investigators. Explain to the chief pilot, in writing if necessary, that you will not supply the recording and that coordination with the Bureau governs the timetable.
Note the tension you may face: a statement given to the operator or its insurer is not privileged in the same way as an investigator's interview. Say only what you observed and did; do not volunteer causal opinions about the operator's maintenance programme.
