Hyderabad: The Director General of Civil Aviation (DGCA) on Monday directed Spicejet to send engine oil samples of its entire Q400 fleet of aircraft to Pratt and Whitney to ascertain the presence of metal and carbon seal particles.
DGCA has also asked Spicejet to draw engine oil samples every 15 days instead of 30 days as is being presently done. The instruction comes following the 12 October "smoke in cabin" incident in the Spicejet aircraft VT-SQB operating from Goa to Hyderabad.
Further, Spicejet has been directed to conduct an inspection of the bleed-off valve screen. In light of the recent incident and also a similar incident in the recent past involving PWC 150A engine, Spicejet has been directed that no engine shall be sent to Standard Aero Singapore till the investigation is completed.
DGCA has asked Spicejet to conduct a one-time boroscopic inspection of all operational engines within a week. The completion of boroscopic inspection on three engines, which were received from Standard Aero, Singapore is to be completed by tonight (Monday night).
Based on DGCA's preliminary investigation, the engine oil entered the Spicejet aircraft's air conditioning system which led to smoke in the cabin. The incident necessitated an emergency landing at Hyderabad. On landing, the passengers were safely evacuated with the assistance of the cabin crew and airport services. DGCA is further investigating the incident.
