Sir - I refer to the report "Oil loss forces down BMA 737" (Flight International, 8-14 March, P16).

When I was an apprentice, my airline did not permit scheduled maintenance on more than one engine per aircraft input, even on three-engine types. At another airline, I was not allowed to work on more than one engine per aircraft input.

Could either of these precautions have prevented the BMA incident? Let us not wait for an extended-range twinjet-operations aircraft to be involved in an incident/accident to force us to re-examine the way in which we operate.
