SWISS Boeing 777-300ER Suffers Bird Strike

Swiss flight number flight LX-40 from Zurich Airport (ZRH) to Los Angeles International Airport (LAX) was unable to complete its return flight to Switzerland following evidence of a bird strike. A Swiss Boeing 777-300, registration HB-JNI had just performed an uneventful 12-hour flight from the Swiss financial center to Los Angeles on Mar 3rd.

When inspecting the aircraft prior to the return leg back to Zurich, aviation website The Aviation Herald reports that the flight was canceled due to evidence of a bird strike.

While no mention as to where evidence of a bird strike was found, it is possible that it was in one of the aircraft’s two General Electric GE90-115BL1 engines. Flight number LX-41 was canceled and the aircraft remained on the ground for 25-hours before being repositioned back to Zurich as flight number LX-5041.

The aircraft, just over two-years-old is configured with 340 seats. It was returned back into service after a further 26-hours on the ground, in Zurich.

A Borescope inspection?

The Boeing 777-300 aircraft is only deemed serviceable when its two engines can provide enough thrust in accordance with the aircraft’s maintenance manual.

If one or several birds were ingested into the engine then it would obviously affect the aircraft’s maintenance load and then the amount of damage found. If on inspection, it is found that there was a bird strike, then a Borescope inspection of the engine core would be required.

While the fan composite blades are very resilient and are able to absorb a bird strike, some may need to be replaced. It is more likely that this incident has affected the outlet guide vane (OGV) or the acoustic liners used to dampen engine noise that needs to be replaced. If there is evidence of foreign object damage (FOD), it is not unusual for an aircraft to be grounded for a day or two as it takes time to get the parts and equipment to check and fix the aircraft.

Originally brought in to replace half of its older Airbus A340 aircraft, the Boeing 777-300ER is seen as being the airlines’ flagship jet. Swiss use the triple seven to fly to long-haul destinations such as Los Angeles, San Francisco, Miami, Montreal, Hong Kong, Singapore, Bangkok, and Sao Paulo.

Swiss and International Women’s Day
