pressurization fault could be recognized by the flight crew. A problem was first noticed when the crew began to feel some discomfort in their ears. This was shortly followed by the cabin altitude warning horn, which indicated that the cabin altitude had exceeded , and this was seen to continue to climb on the cockpit gauge. At the same time, the primary AUTO mode of the pressure control failed, followed shortly by the secondary STBY mode. The crew selected the first manual pressure control mode, but were unable to control the cabin altitude. An emergency descent and subsequent diversion to Lyon was carried out. The failure of the pressurization control system was traced to burnt electrical wiring in the area aft of the aft cargo hold. The wiring loom had been damaged by abrasion with either a p-clip or "zip" strap that, over time, exposed the conductors, leading to short circuits and subsequent burning of the wires. There was no other damage. The wiring for all the modes of operation of the rear outflow valve, in addition to other services, run through this loom. Subsequent developments On 29 August 2005, the company announced successful safety checks on their Boeing fleet, and put them back into service. It later changed its name from Helios Airways to αjet. However, when authorities in Cyprus detained the company's aircraft and froze the company's bank accounts about a year later, the airline announced that it would stop operating on 31 October 2006. In the aftermath of the incident, a number of fake photographs purported to depict the aircraft involved in Helios Flight 522 circulated, and were claimed to be the final photographs of the aircraft before it crashed, taken during its intercept by the Hellenic Air Force. These images, depicting a Boeing 737 of Helios Airways accompanied by F-16s were found to be fabricated; the aircraft depicted in the image is 5B-DBH Zela, a Boeing 737-800 that was in service with Helios at the time of the incident identified by its overwing exits, longer fuselage, and trailing edge wingtips. In March 2011, the Federal Aviation Administration in the United States released an Airworthiness Directive requiring all Boeing 737 aircraft from −100 to −500 models to be fitted with two additional cockpit warning lights. These would indicate problems with take-off configuration or pressurization. Aircraft on the United States civil register were required to have the additional
