Birdstrike

Cessna 152, VH-FUH, 18 km SE Archerfield QLD, 5 September 1989

Summary

The aircraft struck a bird while cruising at 1500 feet. The bird shattered the windscreen and struck the occupants of the aircraft before coming to rest in the rear of the cabin area. The pilot reported that loss of the windscreen reduced aircraft performance to the extent that, while flying at about 1000 feet with cruise power set, the indicated airspeed was 65 knots compared to the normal 90 knots. The bird was later identified as a wedge tailed eagle. It had a wingspan of almost two metres.

Cessna 210M, VH-WRD, Roper River NT, 9 July 1987

Summary

As the aircraft turned onto final, the pilot noticed a large bird (later identified as a kite hawk) above and assessed that the aircraft would pass beneath it. However, the bird rolled over, dived and struck the windshield. The sudden heavy impact smashed the perspex into small pieces which cut the pilot about the face and chest. The broken windshield resulted in a substantial increase in the descent rate which required a considerable increase in power to overcome. A difficult landing was further complicated by a reduction in visibility due to windblast, blood and feathers. Although the pilot's sunglasses and headset were knocked from his head, had he not been wearing glasses it is probable that he would have been blinded as a result of the collision. The specialist ornithologist reported that large birds like kite hawks and eagles have only one evasive manoeuvre and that is to fold their wings and dive. However, if given sufficient warning they will simply turn away from an aircraft. Given that they are adept at avoiding collisions, this bird was caught unawares probably by the low power setting of the engine whilst the aircraft was on approach. When surprised by the proximity of the aircraft it reverted to instinct.

Cessna 207-A, VH-NIV, 20 km E Oenpelli NT, 28 September 1988

Summary

The pilot was conducting a sight-seeing flight and was returning to Jabiru at 6-700 ft above ground level. The pilot recalled seeing a bird just before it impacted the top of the windscreen. The bird did not enter the cockpit but the perspex was shattered. A large piece of windscreen attached to the compass electrical wires swung inwards and hit the pilot across the forehead, nose and mouth. He was wearing sunglasses at the time which may have protected his eyes from the debris. The pilot was able to control the aircraft normally although extra power was required to overcome the increased drag. The aircraft returned safely to the DEPARTURE airfield.

Birdstrike, Boeing 767-338, VH-OGJ, Melbourne Airport, Victoria, on 3 October 2006

Summary

At 1837 Eastern Standard Time on 3 October 2006, a Boeing Co 767-338 aircraft, registered VH-OGJ, with a crew of 11 and 125 passengers, commenced the take-off roll on runway 27 at Melbourne Airport, Vic, on a scheduled passenger service to Sydney, NSW. The sun had set at 1826.

During rotation of the aircraft, the crew noticed a large flock of birds (estimated between 20 and 50 birds) converging with the aircraft's flight path. With no evasive manoeuvre available to the crew at this stage of flight, the aircraft encountered the flock and sustained multiple strikes on many parts of the aircraft. Immediately following the strikes, the crew checked the engine instruments and noticed that the left engine vibration indicator had risen to about 4.5 units. The crew reduced power on the left engine and that reduced the vibration levels. The crew reported that, based on the stable EGT and the vibration level on the left engine being below the limit provided by maintenance watch, they elected to continue the flight to Sydney rather than return to Melbourne.

The investigation found that the decision to continue the flight did not fully take into account the potential effect of the birdstrike on the durability of the left engine, nor did it account for the performance of the aircraft if the right engine ceased operating during the flight.

Following the occurrence, the operator implemented a policy for their twin engine fleet that if a birdstrike to an engine is known to have occurred and there is obvious sign of engine damage, then a landing at the nearest suitable airport should be made.

Safety Action

As a result of the investigation the airport operator advised the Australian Transport Safety Bureau that an improved bird hazard management program had been implemented. It will ensure that bird hazard dispersal measures are conducted within ten minutes of the period prior to the arrival and departure of regular public transport operations during the hours of darkness.

Summary

The Beech 1900D (B1900) accelerated to V1 (111 kts), when the crew noticed a flock of wood ducks crossing their path. At the same time there was a loss of aircraft performance so the crew rejected the take-off. The aircraft was brought to a stop without further incident.

Six wood ducks had impacted the aircraft in the vicinity of the right engine and caused extensive damage to the right engine and wing. Minor damage was evident in the left engine oil cooler.

The Civil Aviation Safety Authority required airports handling aircraft of thirty seats capacity or larger to have a recorded bird hazard management program. At the time of the occurrence, Cooma airport had regular scheduled services by aircraft that did not exceed nineteen persons, however during the ski season aircraft with a capacity exceeding thirty persons operated into Cooma.

Bird dispersal control had been applied early in the morning, approximately twelve hours before the B1900's departure.

Analysis of bird hazard reports since January 2001, indicated an increase in bird numbers at Cooma airport. The airport operator had implemented a bird hazard management program but records showed that the program was not being applied consistently.

Boeing 747SP-38, VH-EAB

Summary

While at approximately 8,000 ft after departure from Sydney, the crew heard a loud bang from the left side of the aircraft. The number 1 engine pressure ratio (EPR) had dropped slightly while the compressor speed (N1), exhaust gas temperature and fuel flow indications increased. The engine vibration level remained within limits. A flight attendant reported seeing something entering into or flaying around the engine intake. After discussions with ground maintenance, the aircraft was returned to Sydney, where an uneventful landing was made after about 50,000 kg of fuel had been jettisoned off the coast.

Examination of the engine by the operator revealed evidence of a bird strike. Blood was found on the engine fan exit nozzle, and the glass-reinforced plastic of the ice impact panel was damaged. About 90 per cent of the circumference of the ice impact panel that covered the acoustic liner aft of the fan was found to be missing

The fan was inspected for damage and the remains of the ice impact panel were removed. (The engine maintenance manual allows the ice impact panel to remain damaged beyond limits or missing for up to 125 hours, or until the next aircraft maintenance inspection.) The EPR probes and their lines were flushed clean and appropriate line connectors were replaced.

A subsequent engine ground run found EPR indications had returned to normal and the engine was cleared back to line operations.

Safety Action

The Australian Transport Safety Bureau (formerly BASI) is conducting a technical analysis of the blade failure. Any safety deficiencies identified will be published in the Bureau's Quarterly Safety Deficiency Report.

Summary

Whilst taxiing for a night departure, the right propeller was struck by a large bird, resulting in the separation of one propeller blade. The ensuing vibration caused substantial damage to the engine mountings and firewall, before the engine could be shut down.

A technical analysis determined that the blade had failed in overload about 15cms from the blade root whilst the propeller was in fine pitch. There was no evidence of any pre-existing cracking or defects in the area which may have contributed to the failure.

The blade had completed 10,228 hours of operation since new and 3,805 hours since last overhaul. The aircraft records indicated that there were no outstanding maintenance requirements on the propeller. The blade complied with all propeller certification requirements.

Witnesses described the bird carcass as that of a Brolga. This species grows to a height of 0.7 to 1.3 metres with a mass of 10 to 15 kilograms.

de Havilland Canada DHC-8-103, VH-JSI, 22 km north-north-east of Broome Aerodrome, Western Australia, on 17 May 1996

Summary

The pilot reported a birdstrike during the descent. The strike appeared to cause the left engine to lose power, and it was shut down and secured. Subsequent investigation indicates that the wiring providing indications to the flight crew was damaged and the instrument indications, only, were lost.

An unsafe left main gear indication illuminated when the gear was selected down for landing. Although the standby system indicated three green lights, a single-engine flypast was completed to confirm the gear position.

The crew did not request emergency services. The company agents on the ground at Broome declined to declare a full emergency and local standby only was activated by airport management.

During the later part of the landing roll the pilot lost directional control of the aircraft. He reported brake and steering failure.

The aircraft veered off the sealed runway before the pilot stopped it by application of the emergency brakes.

Ground witnesses reported the loss of directional control may have been the result of the use of reverse thrust on the remaining operating engine.

There were 17 people on board.
