 AIR CRASH REPORTA report into the cause of an Helios air crash in August last year has concluded that the aircraft crashed because warnings that things were wrong had not been identified, the cabin pressurization selector was in the manual position, the crew was incapacitated because of lack of oxygen and the aircraft ran out of fuel.
The report released on Tuesday, is the result of months of work by the Chairman of the Greek Air Accident and Incidents Investigative Committee Akrivos Tsolakis and his team.
The report also points to deficiencies in the quality, management and safety procedures followed by the operator, to long-term inadequacy on the part of the regulatory authority to meet its safety responsibilities, to the manufacturers inability to take effective measures to rectify previous pressurization incidents and to inadequate application of principles relating to crew resource management.
The report describes the fatal flight on 14 August, 2005 from Larnaca to Prague via Athens which crashed at Grammatiko, north of Athens, killing all 121 people of board, most of them Cypriots.
The report prepared by the Chairman of the Greek Air Accident and Incidents Investigating Committee Akrivos Tsolakis on the cause of the Helios Airways air crash in August 2005 that killed all 121 people on board, says that the Air Accident Investigation and Aviation Safety Board (AAIASB) of the Hellenic Ministry of Transport and Communications investigated the accident following ICAO practices and determined that the accident resulted from direct and latent causes.
According to the report, the direct causes were non-recognition that the cabin pressurisation mode selector was in the MAN (manual) position during the performance of the Preflight procedure, the Before Start checklist and the After Takeoff checklist, non-identification of the warnings and the reasons for the activation of the warnings (Cabin Altitude Warning Horn, Passenger Oxygen Masks Deployment indication, Master Caution), and incapacitation of the flight crew due to hypoxia, resulting in the continuation of the flight via the flight management computer and the autopilot, depletion of the fuel and engine flameout, and the impact of the aircraft with the ground.
The latent causes operators deficiencies in the organisation, quality management, and safety culture, Regulatory Authoritys diachronic inadequate execution of its safety oversight responsibilities, inadequate application of Crew Resource Management principles, and ineffectiveness of measures taken by the manufacturer in response to previous pressurisation incidents in the particular type of aircraft.
The AAIASB further concluded that factors which may have contributed to the accident were omission of returning the cabin pressurisation mode selector to the AUTO position after non-scheduled maintenance on the aircraft, lack of cabin crew procedures (at an international level) to address events involving loss of pressurisation and continuation of the climb despite passenger oxygen masks deployment, and ineffectiveness of international aviation authorities to enforce implementation of actions plans resulting from deficiencies documented in audits.
In the months following the accident, the AAIASB made seven interim safety recommendations, namely five recommendations to the National Transportation Safety Board and to the manufacturer, four of which already resulted in the implementation of corrective actions, one recommendation to the Cyprus Air Accident and Incident Investigation Board and the airlines based in Cyprus, for which corrective action had already been taken, and one recommendation to the Hellenic Civil Aviation Authority (HCAA), which also resulted in the implementation of corrective action.
In addition, the FAA in the United States issued an Airworthiness Directive (AD) which informed flight crews about upcoming, improved procedures for pre-flight setup of the cabin pressurisation system, as well as improved procedures for interpreting and responding to the Cabin Altitude Warning Horn and to the Takeoff or Landing Configuration Warning Horn.
The report also identifies a number of additional safety deficiencies pertaining to maintenance procedures, pilot training, normal and emergency procedures, organisational issues of the Operator, organisational issues related to safety oversight of maintenance and flight operations by Cyprus DCA, EASA/JAA and ICAO, issues related to the aircraft manufacturers documentation for maintenance and flight operations, and issues related to handling by the International Authorities of precursor incident information so as to implement preventive measures in a timely manner.
As a consequence, in its Final Report the AAIASB promulgated an additional eleven safety recommendations, addressed to the Republic of Cyprus, EASA, JAA and ICAO.
In accordance with ICAO Annex 13, paragraph 6.3, copies of the Draft Final Report were sent on 18 May 2006 to the States that participated in the investigation, inviting their comments. The comments sent to the AAIASB by the relevant Authorities in Cyprus, the United Kingdom and the United States were taken into account in the Final Report.
The report, which was given to the press by the Greek side, was presented this morning to Greek Transport Minister Michalis Liapis and the Court of First Instance in Athens. Tsolakis will be arriving in Cyprus later today to present his report to Cypriot President Tassos Papadopoulos, during a special ceremony to be attended by Minister of Communications and Works Haris Thrasou and Chairman of Cyprus Air Crash and Incidents Investigation Committee Costas Orphanos.
The report says that on 14 August 2005, a Boeing 737-300 aircraft, registration number 5B-DBY, operated by Helios Airways, departed Larnaca, Cyprus at 09:07 local time for Prague, Czech Republic, via Athens, Hellas.
The aircraft was cleared to climb to FL340 and to proceed direct to RDS VOR. As the aircraft climbed through 16,000 ft, the Captain contacted the company Operations Centre and reported a Take-off Configuration Warning and an Equipment Cooling System problem.
Several communications between the Captain and the Operations Centre took place in the next eight minutes concerning these problems and ended as the aircraft climbed through 28,900 ft. Thereafter, there was no response to radio calls to the aircraft. During the climb, at an aircraft altitude of 18,200 ft, the passenger oxygen masks deployed in the cabin. The aircraft leveled off at FL340 and continued on its programmed route.
At 10:21, the aircraft flew over the KEA VOR, then over the Athens International Airport, and subsequently entered the KEA VOR holding pattern at 10:38.
At 11:24, during the sixth holding pattern, the Boeing 737 was intercepted by two F-16 aircraft of the Hellenic Air Force. One of the F-16 pilots observed the aircraft at close range and reported at 11:32 that the Captains seat was vacant, the First Officers seat was occupied by someone who was slumped over the controls, the passenger oxygen masks were seen dangling and three motionless passengers were seen seated wearing oxygen masks in the cabin.
No external damage or fire was noted and the aircraft was not responding to radio calls. At 11:49, he reported a person not wearing an oxygen mask entering the cockpit and occupying the Captains seat. The F-16 pilot tried to attract his attention without success. At 11:50, the left engine flamed out due to fuel depletion and the aircraft started descending. At 11:54, two MAYDAY messages were recorded on the CVR.
At 12:00, the right engine also flamed out at an altitude of approximately 7,100 ft. The aircraft continued descending rapidly and impacted hilly terrain at 12:03 in the vicinity of Grammatiko village, Hellas, approximately 33 km northwest of the Athens International Airport. The 115 passengers and six crew members on board were fatally injured. The aircraft was destroyed.
 UNFICYP STATEMENT BUFFER ZONEUNFICYPs objective in managing the buffer zone is to prevent a recurrence of fighting between the opposing forces, says UNFICYP spokesperson in a written statement.
The statement, issued following press reports claiming that UNFICYP has divided the buffer zone, says ``this is clearly false`` and points out ``the article uses a 20-year-old map, which bears no relation to todays realities``.
``UNFICYP is mandated by the United Nations Security Council to manage and patrol the buffer zone, an area defined by operational ceasefire lines`` the statement notes, adding that ``in this context, UNFICYP regulates civilian activity in the buffer zone on the basis of land ownership and security considerations``.
