Narrowly focusing on the proximal means missing the full context. Beware of What-You-Look-For-Is-What-You-Find. “There is almost no human action or decision that cannot be made to look flawed and less sensible in the misleading light of hindsight.”
What Lies Beneath: The Scope of Safety Investigations Read Post »
Research indicates intense commercial pressures, intolerable stress and fatigue, ‘schizophrenic’ simulator sessions and weaponizing of FDM, SMS and ‘fair culture boards’ in a “big brother reality show.” We review a recent paper published in Safety Science.
We discuss the key points from this year’s HeliOffshore conference in Portugal. HeliOffshore is the global collaborative safety association for the offshore helicopter industry.

Accident investigators say a SAR AW101 rolled over “during a period of persistently elevated and confusing operational risk” as the aircraft type was being introduced to military service in Norway.
During the second go-around the crew started an impromptu visual approach when the ExxonMobil installation suddenly came into view. A high ROD at low airspeed developed in low-visibility. The helicopter avoided the sea by just 13 ft. A second loss of control occurred during the ascent.

An ATR72 suffered an uncommanded yaw and roll as it accelerated through 185 knots. The cause was traced to misassembly during a prior maintenance check. A cam in the rudder Travel Limitation Unit could be reversed, and pressures during the check triggered that misassembly.
An engine overdue for overhaul was refitted and 16 months later failed. The operator was not approved for passenger transport but the company was in financial distress so the pilot and part-owner accepted this charter.
BEA were unable to establish the reason for Loss of Control in the hover. The pilot was suffering from an unreported back condition and the HESLO technique required an awkward body position. BEA make recommendations about wellbeing and personal readiness.
A confused response to an engine issue earlier in the day, a sudden power loss and a failed autorotation…but crashing into trees was decisive in the two occupants’ survival say NSIA.

Failure to perform the Descent Check during the approach was a key factor for a loss of direction control after landing. This had “become a fairly common practice among crews”.
A US business jet was operating Part 135 flights with known unresolved maintenance discrepancies and an unqualified flight crew. Due to a brake failure and improper configuration it went off a 50 ft embankment killing the flight crew.
