Hammerton’s Accident Report – Field Worksheet: Form 101

 

Instructions:

 

  1. Investigator In-Charge; IIC:   Your name goes here.

 

  1. The Airline or Registration # and Date of Accident:       self-explanatory.

 

  1. Group Assignments: [as needed]. Due to budget constraints, covid 25, and lack of personnel, you are conducting this investigation alone. However, Someone from the FAA, and each of the parties involved will be available to you. From the actual accident you select use this list as potential ‘talking points’ on your report. Not all will apply.

 

  1. Accident Scene SecuredWas the accident scene secured by the time you arrived? Answer – Yes, No. If in doubt, answer No.

 

  1. PhotographNA – no need to add pictures here. In reality, these pictures would be taken into evidence. For the purpose of this report you may consider what the scene may have looked like and include that in your Factual Findings.

 

  1. Factual Findings: From your Group Assignments Team, which is you, use this list to pull facts from the case. Write a narrative about the factual events leading up to the accident using the list as a guide. This should be less than a page long.

 

  1. Causation: Find the Actual Cause and the Root Cause. Build the chain of causation. Asking the “why” of your Facts (Actual) may help you string and find the Root cause. For example: Saying it was ‘pilot error’ because the pilots crashed their plane’, does not answer the ‘why did they crash their plane’. Causal reasons must be based on facts from your findings. If you cannot answer the ‘why’ of a fact, (the root cause) simply say ‘the cause is undetermined’.

 

  1. Recommendations: This is the most important part of your report. Corrections to safety start with a recommendation. Your recommendations should be relevant and along the chain of causation. Such that if your recommendation is implemented it would have broken the chain of causation and the accident would not have occurred.
