CONFIDENTIAL Check Flight Management
CONFIDENTIAL Check Flight requirement • Boeing Fleet Ø Ø Started as B 737 -300 operator Merged with ‘Go’ BA-funded low cost B 733 operator Converted to all B 737 -700 operator Now being phased out, last 8 reducing to 2 until 2012 • Airbus Fleet Ø Ø Ø 195 deliveries with more orders & options announced Plans for 220+ aircraft fleet Bought GB Airways BA Franchise - A 320/321 Operator (16) Lease & ex-GB aircraft being disposed/EOL 14 EZS aircraft Original aircraft now reaching EOL
CONFIDENTIAL EZY Boeing Event • POSITIONING FLIGHT: • • B 737 -700 End-of-lease “Shakedown” performed on positioning flight Manual Reversion needed 11. 5 turns UP Noted in Check Flight documentation Not recorded in Tech Log as within limits Engineering used data provided to correct Stab. Trim
CONFIDENTIAL EZY Boeing Event • ACTUAL FLIGHT: • • • EZY Customer Demonstration schedule flown Flight combined AMM tasks with Demo Including Manual Reversion Customer Airline reps on flight Limited training for F/O • Previous event: • CAA recognition • Subsequent event: • AMM vs. CDFS
CONFIDENTIAL EZY Boeing Event • Manual Reversion check: • With STAB TRIM, AP TRIM & FLT CONTROL switches OFF: • Dramatic nose-down pitch • Full back stick gave -3100 fpm • Aircraft rolled to 60 degs AOB & control column released (CAA Check Flight Handbook) • FLT CONTROL switches “reinstated” • Still pitching down: 30 deg ND, 447 kts, -20000 fpm • PAN declared • Now IMC at 5600 ft AMSL • FLT CONTROL found OFF and now selected ON
CONFIDENTIAL EZY Event
CONFIDENTIAL EZY Event • UK Air Accidents Investigation Board report: • http: //www. aaib. gov. uk/sites/aaib/publications/bulletin s/september_2010/boeing_737_73 v__g_ezjk. cfm
CONFIDENTIAL What went wrong? • Internally: ØLack of supervision or oversight ØSingle Capt running Boeing Check Flights ØCAA procedures followed rather than AMM ØCombined AMM & Customer flight • Externally: ØNo regulatory requirements ØNo guidance on Demo flights ØE&M handling of reports ØNo formal debrief with Maintenance
CONFIDENTIAL What was changed: • • • Internal Safety Investigation AAIB investigation Check Flight Cell created Oversight & supervision process developed Check Flight Manual created Training & Currency requirements specified Crew requirements specified CDFS schedules redefined & derisked All Airbus Crew attended Airbus Course All flights authorised through ENG & Flt Ops
CONFIDENTIAL CAA FODCOM: CAA Check Flight Definitions: a) Check Flight. A post-certification flight carried out as one of the processes to ensure that the aircraft continues to comply with the applicable airworthiness requirements. b) Elective Check Flight. A Check Flight required by the operator, e. g. to fulfil part of the end of lease conditions. c) Maintenance Check Flight. A Check Flight carried out after maintenance on an aircraft to provide reassurance of performance or establish the correct functioning of a system that cannot be fully established during ground checks. d) Mandated Check Flight. A Check Flight mandated by the CAA mainly associated with the issue of a Certificate of Airworthiness (C of A) for used aircraft imported from outside the European Union.

CONFIDENTIAL Airline issues: • • Issues exist now Commercial pressures (not core business) Availability of Crews Location of Check Flight Positioning of Crews Airspace Engineering delays
CONFIDENTIAL Airline issues: • TFE = ideal scenario • External observer (3 rd seat): Type of Check Flight Crew Maintenance 3 Elective CDFS 2 + Approved Observer Elective other 3 (2 with HOAO approval) CAA mandated 3 • NEVER ideal conditions!
CONFIDENTIAL EZY Airbus Event • Event occurred after new processes: Ø New Capt in Check Flight Cell Ø A 320 IS-ATM Ø Low speed check Ø Conf Clean all satisfactory Ø Conf Full. . .
CONFIDENTIAL EZY Airbus Event CONF FULL Table VMIN 106 kts PFD VMIN 98 kts Buffet felt at 101 kts Full back stick not reached Table Actual
CONFIDENTIAL EZY Airbus Event • • • Check Flight abandoned Airbus consulted FDM data downloaded & analysed Ao. A values frozen 3 x Ao. A gauges changed Successful refly • Crew had completed Airbus Course • Capt very capable • Correct procedures followed
CONFIDENTIAL Further changes: • Guidance from Regulator: Ø Regulation not appropriate Ø Guidance on Demo flight schedules Ø General oversight of process Ø Recognise Operator’s current processes Ø Recognise Course
CONFIDENTIAL Further changes: • Support from Manufacturers Ø Demo flight schedule updates Ø Manufacturers Courses Ø Continuous dialogue Ø Best practice from experts • Support Airbus actions: Ø IS-ATM to Airlines Ø Technical Flight course Ø Continual support & dialogue
CONFIDENTIAL Summary • • High exposure due to Fleet changes Lack of internal & external regulation Internal changes implemented Right Crews & training are key to success • Demonstrated value of correct processes • But learnt the hard way!
