    NTSB Investigating Taxiway Collision at Boston Logan Airport

    The National Transportation Safety Board has opened an investigation into last night’s collision of two jetliners on a taxiway at Boston Logan Airport.

    On July 14, 2011, about 7:33 P.M. EDT, a Delta Air Lines B767-300ER, N185DN, operating as Delta flight 266, was taxiing on taxiway B for departure on runway 04 at Boston Logan International Airport (BOS), when its left winglet struck the horizontal stabilizer of an Atlantic Southeast Airlines CRJ900, N132EV, operating as ASA flight 4904, which was number three in line on taxiway M waiting for departure on runway 09.

    As the B767 approached and passed the intersection with taxiway M, the left winglet of the B767 struck the horizontal tail of the CRJ900. The CRJ900 sustained substantial damage, which included damage to the horizontal tail and vertical tail; the airplane lost fluid in all three hydraulic systems. Parts of the B767 winglet were sheared off and embedded in the tail of the CRJ900. The passengers on the CRJ900 were deplaned on the taxiway, and the B767 taxied back to the terminal.

    Flight data recorders from both airplanes are en route to NTSB headquarters. Air Safety Investigator Dan Bower is the Investigator-In-Charge. Parties to the investigation include Delta Air Lines, Atlantic Southeast Airlines, the Federal Aviation Administration, and the Air Line Pilots Association.

    NTSB Warns Old Weather Data on Pilot Displays Can Contribute to Plane Crashes

    The NTSB has sent out a safety alert concerning weather information that is up to twenty minutes old, although it may be advertised as real time data. The discrepancy in time can be fatal when weather conditions are in rapid flux. The NTSB has related this old weather information to two recent crashes that occurred at night:

    • March 2010 med-evac helicopter Tennessee crash where the pilot was racing to home base trying to beat a storm
    • December 2011 Piper PA-32 Bryan Texas where the plane broke up in stormy weather.

    In both these crashes, “the time stamps indicated the one-minute time interval used to create the image, and not the actual age of the data used to create the image.”

    The Tennessee crash involved information five minutes old; the Texas crash involved information six to eight minutes old.

    The night crashes in particular are affected by old data. Pilots need to be aware that the data can be old, and not use the weather display to navigate around bad weather.

    Slow ID in November 2013 LAM Crash

    Identification of the remains of those aboard the LAM Embraer-190 that crashed en route from Maputo to Luanda is moving at a snails pace. Sixteen of the 33 fatalities have been identified, mostly, according to police reports, by fingerprint evidence.

    The scientists who are making the identification are working with fragments.

    I am not a scientist, and it does not appear that the scientists in this case are using DNA identification. But I did uncover an article here where a forensic scientist explicitly lists the time it takes for DNA identification. This reference might prove useful in providing some kind of framework to the families who are waiting for remains of their recently lost family members to be identified if the Mozambique investigation turns to DNA identification. The families have been waiting since the date of the crash, 29 November 2013.

    The cockpit voice recorder (CVR) and the flight data recorder (FDR), were recovered from the crash site within four days of the crash. But the preliminary report only says:

    NTSB Identification: DCA14RA018
    Accident occurred Saturday, November 30, 2013 in Rundu, Namibia
    Aircraft: EMBRAER ERJ190 – UNDESIGNAT, registration:
    Injuries: 33 Fatal.
    This is preliminary information, subject to change, and may contain errors. The foreign authority was the source of this information.

    The Namibia Ministry of Works and Transport (MWT) has notified the NTSB of an accident involving an Embraer ERJ-190 that occurred on November 30, 2013. The NTSB has appointed a U.S. Accredited Representative to assist the MWT investigation under the provisions of ICAO Annex 13 as the State of Manufacturer and Design of the engines.

    All investigative information will be released by the MWT.

    NTSB Safety Recommendation


    The National Transportation Safety Board makes the following recommendations to the Federal Aviation Administration:

    Require that Avions de Transport Régional (ATR)42-seriesairplanes operating in the United States incorporate a revised stickpusher activation angle of attack(AOA), such that the stick pusher activates before the stall AOA in the presence of airframe ice accretions. (A-12-24)

    Evaluate all U.S.-certificated transport-category airplanes equipped with stick pushers to ensure that the stick pusher
    activates at an angle of attack that will provide adequate stall protection in the presence of airframe ice accretions.(A-12-25)

    LionAir Flight Updated


    On the flight prior the LionAir accident flight on the Boeing Max registered as PK-LQP, an off-duty fully-qualified Boeing 737-MAX 8 pilot was traveling home on flight JT-43. The plane encountered problems similar to the next flight that crashed it (i.e. the LionAir accident flight from Denpasar to Jakarta.) The crew aboard the earlier flight managed to land the aircraft at the destination. Based on the crew’s entry in the AFML, the engineer at Jakarta flushed the left Pitot Air Data Module (ADM) and static ADM to rectify the reported IAS and ALT disagree and cleaned the electrical connector plug of the elevator feel computer. The aircraft was subsequently released to carry out flight JT610.(A different crew manned the fatal flight.) The pilot was interviewed by the Kantor Komite Nasional Keselamatan Transportasi–Ministry of Transportation of the Republic of Indonesia (KNKT). The KNKT committee is responsible for investigating and reporting air transportation system accidents, serious incidents and safety deficiencies involving air transportation system operations in Indonesia.

    The KNKT estimates that the release of the final report for Lion B38M in August or September 2019.

    The KNKT is cooperating with Ethiopian Authorities but will make no official comment. News media reports suggest that on the earlier LionAir flight, a third pilot had occupied the observer’s seat in the cockpit of flight JT-43 and that this pilot identified the automatic trim runaway issue at hand and initiated that the trim cut out switches be used.

    The preliminary report on the LionAir crash is located HERE.
