Why should the guy who did it automatically lose his job??
Accidents happen all the time and if aircrew got the sack everytime they cocked up, we would be really short on drivers!!!
Seriously, a policy like that only encourages anyone who accidently damages an aicraft in the course of their job to try and cover it up rather than come clean.
Each incident should be treated on its merits and staff should always be treated fairly. That way all accidents will be reported however small.
