AAIB Field Investigations
A field investigation is an independent investigation in which AAIB investigators collect, record and analyse evidence.
The process may include, attending the scene of the accident or serious incident; interviewing witnesses; reviewing documents, procedures and practices; examining aircraft wreckage or components; and analysing recorded data.
The investigation, which can take a number of months to complete, will conclude with a published report.
