From ‘The Naked Pilot’ by David Beaty
Firstly, there should be an acknowledgment that if and when the pilot makes a mistake, his will probably be the final enabling one at the apex of a whole pyramid of errors down below. This will, in turn, take the heat off investigations – the ‘we intend to find and punish the culprit’ syndrome. Only then can the pilots come forward and admit to mistakes they made or nearly made, and the reasons why can be coolly analysed and lessons learned. [Page 285]
Professor Reason in Human Error (1990) distinguishes between active error, the effects of which are felt almost immediately, and latent error, the adverse consequences of which may lie dormant within the system for a long time. This can clearly be seen in aviation, where pilots at the sharp end make an active error, while latent error lies behind the lines within the management support system. Many of these are already there awaiting a trigger, usually supplied by the pilot. ‘There is a growing awareness within the human reliability community that attempts to discover and neutralise those latent failures will have a greater beneficial effect upon system safety than will localised efforts to minimise active errors.’
As long ago as 1980, Stanley Roscoe wrote that:
The tenacious retention of ‘pilot error’ as an accident ‘cause factor’ by governmental agencies, equipment manufacturers and airline management, and even by pilot unions indirectly, is a subtle manifestation of the apparently natural human inclination to narrow the responsibility for tragic events that receive wide public attention. If the responsibility can be isolated to the momentary defection of a single individual, the captain in command, then other members of the aviation community remain untarnished. The unions briefly acknowledge the inescapable conclusion that pilots can make errors and thereby gain a few bargaining points with management for the future.
Everyone else, including other crewmembers, remains clean. The airline accepts the inevitable financial liability for losses but escapes blame for inadequate training programs or procedural indoctrination. Equipment manufacturers avoid product liability for faulty design,. Regulatory agencies are not criticised for approving an unsafe operation, failing to invoke obviously needed precautionary restrictions, or, worse yet, contributing directly by injudicious control or unsafe clearance authorisations. Only the pilot who made the ‘error’ and his family suffer, and their suffering may be assuaged by a liberal pension in exchange for his quiet early retirement – in the event that he was fortunate enough to survive the accident
Yet it is only recently that very dubious management malpractices are being identified and their contribution to accidents given sufficient weight. For though the pilot’s actions are at the tip of the iceberg of responsibility, many other people have had a hand in it – faceless people in aircraft design and manufacture, in computer technology and software, in maintenance, in flying control, in accounts departments and in the corridors of power. But the pilot is available and identifiable. [Page 221/222]
An incident/accident is generally the result of active failures (pull the trigger) on the part of the cockpit crew, but the stage may have been set by the latent failures (load the gun and put the safety catch to ‘fire’) introduced by others (management practices, certification standards, aircraft design, software, ergonomics etc etc). Put another way, the cockpit crew is the last line of defence for every ones mistakes. As good as you may think yourself, none of us are all knowing.
Capt. Fenwick of ALPA has cautioned. "Pilots will be judged against the perfect pilot flying the perfect airplane on the perfect flight. We all know that no such thing exists.”
What would EK's response be to the above?
