    DGCA Gulf Air Landing Examined

    What: Gulf Air Airbus A320-200 en route from Bahrain to Kochi, India
    Where: Kochi
    When: Aug 28th 2011, 3.55 am
    Who: 137 passengers and 6 crew, 8 injuries
    Why: In examining this August incident, after doing some runway testing, the DGCA is blaming the accident on a slick runway.

    However defects have been found in the plane’s front wheel. And the statement of the DCGA’s opinion also mentions pilot error. So they have released a statement combining pilot error, plane flaws and a bad runway as being behind the runway excursion.

    Can a pilot land on a slick runway? What exactly was the pilot’s error in this situation? Does the entire runway have the identical friction coefficient or just the area tested? Runway friction is also going to be affected by the condition of the tires; what was the condition of the tire before it blew? Inquiring minds want to know.

    Airport testing at Cochin airport revealed airport friction level.

    A C K Nair, director of the Cochin airport made the following defensive statement:

    “As per the International Civil Aviation Organisation’s (ICAO) norms the friction coefficients of the runways should not go below 0.34, while the value was 0.61 to 0.86 till recently. On the day of the mishap the average value was hovering between 0.52 and 0.84. The value at the spot where the ill-fated aircraft touched the runway was 0.75 to 0.85. We did another test on September 3 and the value was above 0.5.’

    American Airlines Emergency Landing in Dallas, Engine alert, Tire Pop

    What: American Airlines Boeing 777 en route from Dallas to Sao Paolo, Brazil
    Where: Dallas
    When: July 31, 2011
    Who: 264 passengers, 14 crew
    Why: Indicators convinced the pilots of Flight 963 that an engine caught on fire. The pilots returned to Dallas and landed the 777 safely. The brakes locked up and a tire blew out, but that kind of thing is not unusual for an overweight landing.

    Onlookers saw the flight dumping fuel, described as fuel streaming from its jets. If they were alarmed, just think how the passengers felt.

    In George’s Point of View


    At least they survived. For what they put the passengers through, what will the airline operator do? Will they hand out to the passengers a free drink voucher? A hundred dollar voucher for future use?
    I want to know.

    What: Air Transat Airbus A330-300 en route from Toronto to Dublin
    Where: Toronto
    When: Jul 15th 2011
    Who: 314 passengers
    Why: During takeoff, a tire was damaged. The tire caused damage to several parts of the plane, which initially had been attributed to a bird strike. Tire debris (tread) was found on the runway.

    The flight continued to Dublin, where the plane made a safe landing on a tire which had lost tread. On inspection, it was found that a wing panel and a landing gear door needed repair, having been damaged on takeoff by tread.

    A replacement flight was sent to Dublin to make the return flight.

    Where: Dubai
    When: Jun 8 2011
    Why: During takeoff from Dubai, the left and right nose gear tire burst. (For whatever reason, the first tire burst, the second probably burst due to the increased weight.)

    The plane rejected takeoff, and came to rest on the runway with overheated brakes that were handled by emergency services. The plane was towed off the runway, and passengers were provided an alternative flight.

    Contact photographer Andreas Mueller – Spotterteam Graz

    What: KLM Boeing 777-200 en route from Atlanta,GA to Amsterdam
    Where: Amsterdam
    When: Feb 3
    Why: After a successful flight from Atlanta to Amsterdam, the flight crew reported a flat tire prior to landing.

    * (The plane’s indicators include a tire pressure indicator. As a rule, when 5 of the 6 main landing gear tires are correct, the pressure is adequate for landing.)

    However, they made a successful landing and taxied to the gate.

    Emergency Landing in Darfur

    What: Tarco Airlines Antonov AN-24 en route from Nyala to Zalingei
    Where: Zalingei City, Darfur, Suden
    When: Nov 11th 2010
    Who: 44 passengers and 6 crew
    Why: A plane on a peacekeeping mission landed, apparently with an explosion on the side of the plane; two tires burst and caught fire. The fire resulted in from 6 to 15 fatalities, 6 injured. Rported numbers on casualties vary greatly. It is also reported that only 11 survived and that only 6 were killed. CNN did not mention a peacekeeping mission, but said the passengers were returning for a holy day with their families at the end of Ramadan.

    So in conclusion-we can just say that something happened, but we’re not exactly sure what, at least not until official reports come out.

    Contact photographer Marcelo Magalhaes

    What: Varig Logistica Boeing 757-200 freighter en route from Manaus to Sao Paulo
    Where: Manaus
    When: Nov 10th 2010
    Who: 2 crew
    Why: While lining up for departure, a freighter loaded with 30 tons of goods to Sao Paulo got stuck on the runway when two main gear tires deflated. Rain and the beached plane effectively disabled most of the runway for several hours.

    George’s Point of View

    Maintenance, Maintenance, Maintenance
    I find the timing of this incident extremely ironic, when noticing that today we have also received and published a press release highlighting how the “Goodyear Expert Cites Tips for Proper Aircraft Tire Maintenance,” a press release showcasing a Goodyear Tires Product Support Manager’s Tire maintenance manual. It even has photo sections for aviation “tire whisperers” who want to recognize what happened to a tire by the visible damage.

    You would think that we would know tires get flat by now, if only from our experience of all the cars on the road.

    Flat Tire at Patna

    What: Air India Airbus A320-200 en route from Delhi to Patna
    Where: Patna
    When: Oct 26 2010
    Why: A runway inspection indicated a runway inspection at Delhi indicated debris on the runway, and that on takeoff, several runway edge lights had been destroyed, presumably from the takeoff of the Air India Airbus A320-200. The runway had to be closed for repairs.

    On landing at Patna, a tire burst on the Airbus. It is presumed that the runway edge lights may have caused some preliminary damage to the tires.

    George’s Point of View

    *Note to pilot: repeat 3 x: runway lights are not speed bumps.
