I have looked through this thread with interest. Whilst in some peoples mind there may be confusion about who was P1 surely that would be cleared up by looking at who signed the Tech Log accepting the a/c. In my world the P1(Captain) always signs the tech log.

AllyPally, this is what is stated in the AAIB Report:
Extract from the AAIB Report:
Whilst no technical defect was determined as being a causal factor in this accident, the absence of technical records referred to in the aircraft’s log book meant that the aircraft operator had not complied with the requirements of the ANO. However, the available documentation indicated that the aircraft had been maintained in accordance with the requirements.
Suggests absence of the actual Tech Log, or missing information from the Tech Log, which is why it is only assumed that Andrew Walker was P1, not confirmed.
