Would you allow a passenger to 'have a go' on the controls?
This post is deliberately vague to disidentify the event in question since it's not really pertinent to the main point. I had no involvement.
Following the accident, in which nobody was injured, the loss adjuster (LA) interviewed the pilot (not an instructor) and passenger from the single engine light aeroplane. By all accounts the LA was a friendly outgoing chap and chatted to quite a few other people before leaving. The LA determined from 'loose tongues' that the passenger (a qualified pilot but not listed as a pilot on the syndicate’s insurance policy) had, for at least part of the flight, handled the controls. Consequently the insurer voided the policy leaving the pilot liable for life-changing amounts of money to her/his syndicate partners and others.
Have you ever allowed a passenger, qualified or otherwise, to handle the controls on an SEP whilst you are PIC? If so would you do it again?
