Safety Recommendation Details

Safety Recommendation A-16-020
Synopsis: On March 5, 2015, at 1102 eastern standard time, Delta Air Lines flight 1086, a Boeing MD-88, N909DL, was landing on runway 13 at LaGuardia Airport (LGA), New York, New York, when it departed the left side of the runway, contacted the airport perimeter fence, and came to rest with the airplane’s nose on an embankment next to Flushing Bay. The 2 pilots, 3 flight attendants, and 98 of the 127 passengers were not injured; the other 29 passengers received minor injuries. The airplane was substantially damaged. Flight 1086 was a regularly scheduled passenger flight from Hartsfield-Jackson Atlanta International Airport, Atlanta, Georgia, operating under the provisions of 14 Code of Federal Regulations Part 121. An instrument flight rules flight plan had been filed. Instrument meteorological conditions prevailed at the time of the accident.
Recommendation: TO THE FEDERAL AVIATION ADMINISTRATION: Collaborate with Boeing and US operators of MD-80 series airplanes to (1) conduct a study to examine reverse thrust engine pressure ratio (EPR)-related operational data, procedures, and training and (2) identify industry-wide best practices that have been shown to be effective in reliably preventing EPR exceedances to mitigate the risks associated with rudder blanking.

Safety Recommendation History
From: NTSB
Date: 3/27/2017
Response: We note that you are working with US MD-80 operators and Boeing to identify operational procedures regarding the amount of reverse EPR to be used when landing and to develop training to address rudder blanking. Additionally, you plan to identify best practices to prevent EPR exceedances and mitigate the risks associated with rudder blanking. We further note that you participated in a January 12, 2017, meeting held in Las Vegas with Boeing and US MD-80 operators to discuss this and related NTSB recommendations. Pending completion of the recommended action, Safety Recommendation A 16 20 is classified OPEN--ACCEPTABLE RESPONSE.

From: FAA
Date: 12/27/2016
Response: -From Michael P. Huerta, Administrator: The Federal Aviation Administration (FAA) identified operators ofMD-80 series airplanes and plans to reach out to a selected group of operators to have them identify: • Their documented operational procedures for the amount of reverse EPR to be used on landing: • Their documented training to address rudder blanking; and • A point of contact at the air carrier for further discussions on this topic. We also established communication with Boeing regarding this recommendation. Once we identify the remaining parties and receive the information we requested from the operators, we will collectively discuss the feasibility of the recommended study and identify any best practices to prevent EPR exceedances and mitigate the risks associated with rudder blanking.
