On 1 November 2021, a deHavilland DHC6-300 crew en-route to Fort Simpson realised that they had insufficient fuel on board to reach their intended destination and therefore decided to attempt a diversion to the nearest available airport at Fort Providence. As fuel available dwindled, one engine was shut down but after an inadvertent fuel tank selection, the initially intended diversion was no longer possible and a forced landing in a bog was successfully accomplished. The Training Captain involved had developed a habit of performing checklists silently and from memory after gaining all his professional pilot experience at the same operator.

On 1 December 2021, a lightly loaded Boeing 737-800 became airborne near the end of the runway at Kuusamo with only engine run-up thrust set with only the abnormally low climb rate alerting the crew to their error. Serial failure by both pilots to follow relevant normal takeoff procedures followed after the type-experienced First Officer had been surprised when the aircraft began to move because his inexperience in brake use resulted in insufficient brake pressure being applied during the engine run-up. The Captain’s failure to notice the error was associated with allowing himself to be distracted by a non-urgent radio call.

On 6 January 2018, a Boeing 737-900 and an Airbus A320 both inbound to Surabaya with similar estimated arrival times were cleared to hold at the same waypoint at FL100 and FL110 respectively but separation was lost when the A320 continued below FL110. Proximity was limited to 1.9nm laterally and 600 feet vertically following correct responses to coordinated TCAS RAs. The Investigation found that all clearances / readbacks had been correct but that the A320 crew had set FL100 instead of their FL110 clearance and attributed this to diminished performance due to the passive distraction of one of the pilots.

On 16 June 2021, a Boeing 737-400 was taxiing for departure at night after push back from stand when the ground crew who completed the push back arrived back at their base in the tug and realised that the tow bar they had used was not attached to it. The aircraft was prevented from taking off and it was then found that it had taxied over the unseen towbar and sustained damage to both nose gear tyres such that replacement was necessary. The Investigation concluded neither ground crew had checked that the area immediately ahead of the aircraft was clear.

On 3 January 2019, prescribed vertical separation was lost between a Bombardier DHC8-400 and a Piaggio P180 on converging cruise tracks at FL 220 and only restored after a resulting TCAS RA was followed. The Investigation found both aircraft were being flown in accordance with their clearances and that the controller involved had not been aware of corresponding traffic and conflict alerting system activations. A specific traffic display fault which arose from failure to follow a routine software upgrade procedure correctly and the shift supervisor failing to recognise the need to act as controller when workload increased were assessed contributory.

On 7 November 2018, a Boeing 747-400F overran wet landing runway 14 at Halifax at night and was sufficiently damaged as a result of exceeding the available RESA to render it a hull loss. The Investigation attributed the overrun to a combination of factors including use of un-factored landing distance, momentary mishandling of the thrust levers just after touchdown, a pilot-caused lateral deviation diverting attention from deceleration, inadequate braking and late recognition of an approach tailwind component. Poor NOTAM presentation of runway availability also led the crew to believe that the longer and more suitable runway 25 was not available.

On 2 September 2016, an ATR72-600 cleared to join the ILS for runway 28 at Dublin continued 800 feet below cleared altitude triggering an ATC safe altitude alert which then led to a go around from around 1000 feet when still over 5nm from the landing runway threshold. The Investigation attributed the event broadly to the Captain’s inadequate familiarity with this EFIS-equipped variant of the type after considerable experience on other older analogue-instrumented variants, noting that although the operator had provided simulator differences training, the -600 was not classified by the certification authority as a type variant.

On 15 November 2018, a Bombardier DHC8-300 made a main gear only touchdown at Stephenville with only minor damage after diverting there when the nose landing gear only partially extended when routinely selected on approach at the originally intended destination. The Investigation found that the cause was incorrect nose gear assembly which had allowed hydraulic fluid to leak and eventually led to it jamming. There was some concern at the way the flight was conducted following the problem which involved continuous smartphone communications with the operator and an overspeed which it was considered constituted an avoidable risk to safety.

On 27 April 2020, an ATR 72-200 freighter crew attempted a night takeoff in good visibility aligned with the edge of runway 06 and did not begin rejecting it until within 20 knots of the applicable V1 despite hearing persistent regular noises which they did not recognise as edge light impacts and so completed the rejection on the same alignment. The Investigation noted both pilots’ familiarity with the airport and their regular work together and attributed their error to their low attention level and a minor distraction during the turnround after backtracking.

On 2 February 2019, a Bombardier CRJ200 narrowly avoided collision with part of a convoy of snowplough vehicles which entered the landing runway at Montreal without clearance less than 10 seconds before touchdown and begun to position on the centreline. The Investigation found that despite the prompt initiation of a go-around on sighting the vehicles, the aircraft was likely to have cleared them by less than 100 feet. A number of opportunities for improved ground vehicle movement procedures were identified and the incursion was seen as indicative of a general need to more effectively address this risk at Canadian airports.

On 24 November 2019, as an Airbus A321 taking off from the 2665 metre-long runway 05 at Glasgow approached the calculated V1 with the flex thrust they had set, the aircraft was not accelerating as expected and they applied TOGA thrust. This resulted in the aircraft becoming airborne with less than 400 metres of runway remaining. The Investigation confirmed what the crew had subsequently discovered for themselves - that they had both made an identical error in their independent EFB performance calculations which the subsequent standard procedures and checks had not detected. The operator is reviewing its related checking procedures.

On 28 April 2018, a Boeing 737-800 exited the landing runway at Perth and without clearance crossed a lit red stop bar protecting the other active runway as another 737 was accelerating for takeoff. This aircraft was instructed to stop due to a runway incursion ahead and passed 15 metres clear of the incursion aircraft which by then had also stopped. The Investigation concluded that, after failing to refer to the aerodrome chart, the Captain had mixed up two landing runway exits of which only one involved subsequently crossing the other active runway and decided the stop bar was inapplicable.

On 19 January 2010, PSA Airlines CRJ 200 began take off from Charleston with an incorrect flap setting. After late crew recognition, a rejected take off was commenced at V1+13KIAS and an overrun into the EMAS bed at approximately 50knots followed. It was noted that had the overrun occurred prior to installation of the EMAS bed, the aircraft would probably have run down the steep slope immediately after the then-available RESA. The flap setting error was attributed non-adherence to a sterile flight deck. The late reject decision to an  initial attempt to correct the flap error during the take off.

On 24 May 2010 the crew of a Regional Embraer 145 operating for Air France continued an unstable visual approach at Ljubljana despite breaching mandatory go-around SOPs and ignoring a continuous EGPWS PULL UP Warning. The subsequent touchdown was bounced and involved ground contact estimated to have been at 1300fpm with a resultant vertical acceleration of 4g. Substantial damage was caused to the landing gear and adjacent fuselage. It was concluded that the type-experienced crew had mis-judged a visual approach and then continued an unstabilised approach to a touchdown with the aircraft not properly under control.

On 29 March 2010, a Raytheon 390 operating a passenger charter flight failed to follow acknowledged taxi instructions in normal visibility at night and entered the departure runway at an intermediate intersection and turned to backtrack against an opposite direction CRJ200 which had just started its take off roll. There was no ATC intervention but the CRJ crew saw the aircraft ahead and were able to stop before reaching it. The Raytheon flight crew stated that they had “encountered considerable difficulties finding out where they were while taxiing” and ended up on the departure runway “without realising it”.
