Slippery runway & more so the safety area at Kozhikode may be a leading cause of the Air India Express crash

Image
RESA  The entire state machinery is on overdrive to defend the Calicut Airport stating that it was completely safe for flight operations. There are two significant points to focus on while determining the causes of the accident.  1. Previous safety audits have pointed to vegetation on the runway end safety area (RESA). 2. The rubber deposits at the ends of the runway may have been a contributory cause of the accident. Comparison A comparison of the runway friction values indicates a possibility of higher rubber deposits or poor runway friction levels at both ends of the runways. A friction level below 0.47 requires maintenance action as per the Indian Aeronautical Information Publication. The combination of runway friction and vegetation on the RESA may have been a significant factor that may have caused the Air India Express 1344 runway overrun at Kozhikode on 7th Aug 2020. Must note that the runway has a pronounced crown close to the middle and drops more than 25 feet on either side.

  Air Djibouti the African Airline, Boeing B-737 suffered a landing gear collapse on landing at Garowe airport, Somalia. No injuries have been reported. AvHerald reports: An Air Djibouti Boeing 737-500, registration EY-560 performing flight IV-206 from Hargeisa (Somaliland/Somalia) to Garowe (Puntland/Somalia) with 39 passengers and 5 crew, landed at Garowe (capital of Puntland) Airport's runway 04 at about 09:30L (06:30Z) but suffered the collapse of the right hand main gear at low speed. The aircraft veered to the right but came to a stop within the runway edge resting on right hand engine, left main and nose gear. There were no injuries, the passengers disembarked/evacuated onto the runway and were taken to the terminal. The flight had originated in Djibouti (Djibouti) and was destined for Mogadishu (Somalia) with intermediate stops in Hargeisa and Garowe. Garowe International Airport features an asphalt runway 04/22 of 2000 meters/6600 feet length. Local Media report the airpor

Boeing risk assessment had predicted 15 B737 Max accidents & 2900 deaths, was it acceptable to the DGCA?

  The final committee report prepared by the USA committee on transport and infrastructure has carried out a comprehensive study on the design development and certification of the Boeing 737 Max based on the facts & data when it was certified to fly for the first time. There were two tragic accidents which followed , in quick succession which everyone will remember, the Lion Air and the Ethiopian airways. The B737 Max fleet was grounded worldwide. There are a number of startling yet expected conclusions that the report draws but there is one which no one must ignore. "In December 2018, the FAA conducted a risk assessment based on its Transport Aircraft Risk Assessment Methodology (TARAM) and estimated that without a fix to MCAS, during the lifetime of the 737 MAX fleet, there could potentially be 15 additional fatal crashes resulting in over 2,900 deaths ." Read the full report here.. Slide 1 The obvious question, why weren't the aircrafts grounded? The Boeing officia

FAA proposes draft B-737 Max Training only for US carriers & registered aircraft only

B737 Max Flight Simulator  The FAA has released a f light standardisation board report relating to B-737 Max pilot training. Soon after, an addendum was issued too.  While FAA has clearly stated that the training required in the FSB is mandated for US air carriers & US registered aircrafts, other aviation authorities must take their own action for the return of the B-737 Max. Question, will the Indian regulator follow a systematic process of change management and not be rushed into the re-entry process? Will the FSB report adopted in toto and will the regulators draft training requirements be put out for public comments? The key highlights are quoted below from the FAA website as of 7th Oct 2020: While this is an important step, several key milestones remain: Final Design Documentation and Technical Advisory Board (TAB) Report  – The FAA will review Boeing’s final design documentation to evaluate compliance with all FAA regulations. The multi-agency TAB will also review the fi
