                              Pre Flight External Check by  Fight Crew   is part of the basis for the Captain's Aircraft Acceptance which must be formally recorded in the  Aircraft Technical Log  prior to every flight departure. It is primarily, therefore, a general visual inspection of those aspects of fitness of the aircraft for flight which can be verified wholly or partly in that way. Incidentally it also provides an opportunity to observe the environment in which the aircraft is parked and may sometimes allow the observation of aspects of aircraft hold loading and routine aircraft servicing. It is entirely unrelated to the separate requirements for appropriately qualified aircraft maintenance technicians to carry out scheduled checks and inspections necessary for the  Certificate of Release to Service  to be signed and, in some cases, to remain valid for the specif...

       As part of the Accident Prevention Programme following steps have been taken to avert the recurrence of air mishaps and impending eventualities at airports in the country: • Accident / incident data is regularly analyzed and based on the analysis, Air Safety Circulars are issued to bring important observations/findings to the notice of the operators to avoid the recurrence of the accidents. • Recommendations emanating from the accident/incident investigation reports are implemented to prevent such mishaps. • As per the annual surveillance programme, audit of the operators are carried out. Recommendations emanating from such reports are followed up with the operator for implementation. The compliance of the action taken by the operator is further verified during the next audit.The Government appoints various Committees of Inquiry as per the provisions of Aircraft (Investigation of Accidents and Incidents) Rules, 2012 to investigate the aircraft accidents ...

              Airports Authority of India (AAI) has prepared Colour Coded Zoning Maps (CCZM) of airports of Delhi and Mumbai clearly indicating the permissible heights in different colour coded grids in different zones of these airports. These maps are available on AAI's website.                   It has been decided to upgrade the existing online height clearance system i.e. NOCAS to NOCAS V.2. The NOCAS V.2 is bound to process the NoC application without any human intervention after physical verification of site elevation and co-ordination by AAI officials and issuance of NoC for height clearance expeditiously.              

          Minister of Civil Aviation Shri Ashok Gajapathi Raju while Chairing the meeting of the Parliamentary Consultative Committee on Safety Measure in Civil Aviation Sector informed the Members that the Government has a plan to create a “Civil Aviation Authority of India” in place of DGCA to ensure efficiency in its procedures with ease of recruitment of skilled manpower. It will strengthen the system’s ability to cope with emerging safety challenges of the growth of the sector in the long run.         He added DGCA has issued various regulations for carrying out India’s obligation to the Chicago Convention and advisories to the industry regarding election flying, seasonal helicopter operations, real time tracking of the aircrafts etc. In accordance with the standard and recommended practices of ICAO, DGCA has developed State Safety Programme for India which is available on DGCA website. In accordance with the ICAO SARPs, India has al...

           Air India has made psychometric test mandatory for the recruitment of Trainee Pilots (Commercial Pilot License Holders). However, candidates recruited as Cabin Crew are not subjected to any psychometric test. The recruitment test for the post of Trainee Cabin Crew was conducted by Indian Institute of Psychometry on 11th January, 2015 at Delhi and Chennai. As many as 401 candidates were called for the written test and 394 candidates appeared, out of which 357 candidates qualified the same. No change in the medical standards of pilots is proposed as they are in line with ICAO requirements. However, many airlines are carrying out psychometric test of pilots at the time of induction. This information was given by Minister of State for Civil Aviation, Dr. Mahesh Sharma in a written reply in the Rajya Sabha today.

Verify correct directional travel of controls and trim                 The problem               Incorrect rigging of flight control and trim systems has led to in-flight emergencies, accidents,     and even deaths.               Four such mishaps within a 2-year span share common safety issues:    o Maintenance personnel who serviced or checked the systems did not recognize that the             control or trim surfaces were moving in the wrong direction.    o Pilots who flew the airplanes did not notice the control anomalies during their preflight                   checks.              Anyone can make mistakes. In some cases, the mechanics who performed the work   incorrectly were highly experienced. Related incident and accident...

               When an owner/operator arranges for the relevant maintenance organisation to retain  copies of the continuing airworthiness records on their behalf, the owner/operator will  continue to be responsible for the retention of records. If they cease to be the  owner/operator of the aircraft, they also remain responsible for the transferring the  records to any other person who becomes the owner/operator of the aircraft.                Keeping continuing airworthiness records in a form acceptable to DGCA normally means in paper form or on a computer database or a combination of both methods . Records stored in microfilm or optical disc form are also acceptable.                All records  should remain legible throughout the required retention period.  Paper systems should use robust material, which can withstand normal han...

Current status of AD should identify the applicable AD including revision or  amendment numbers. Where an AD is generally applicable to the aircraft or  component type but is not applicable to the particular aircraft or component, then this  should be identified.   AD Status includes the date when the AD was  accomplished, and where the AD is controlled by flight hours or flight cycles it should  include the aircraft or engine or component total flight hours or cycles, as appropriate. Repetitive ADs , only the last application should be recorded in the AD status. The  status should also specify which part of a multi-part directive has been accomplished  and the method, where a choice is available in the AD. Status of current modification and repairs means a list of embodied modification  and repairs together with the substantiating data supporting compliance with the  airworthiness requirements. This can be in the form of ...
