Change of door design
Tillaga í öryggisátt
The Icelandic Transportation Safety Board (ITSB) recommends to Precision Conversions that it reviews the structural design of the main cargo door with respect to the 45 knots maximum wind operation loading and make the necessary design changes in order to meet the requirements of FAA FAR and EASA CS, subchapters 25.301(a) and 25.303.
Afgreiðsla
Precision Conversions has modified the structural design of the main cargo door to support the intended 45 knots maximum wind operation limit in compliance with FAA FAR and EASA CS, subchapters 25.301(a) and 25.303.
EASA mandate of design change to cargo door due to maximum wind operation loading
Tillaga í öryggisátt
The Icelandic Transportation Safety Board (ITSB) recommends to EASA that it require the STC holder of EASA STC EASA.IM.A.S.01423 to review the structural design of the main cargo door with respect to the 45 knots maximum wind operation loading and make the necessary design changes in order to meet the requirements of EASA CS, subchapters 25.301(a) and 25.303.
Afgreiðsla
The STC holder addressed through service bulletin (SB) PC-757-52-0018 a redesign of the cargo door, replacing the aluminum rods of the door with steel rods.
In addition, for both configurations, pre and post SB PC-757-52-0018, the following wind/gust limitations have been established and incorporated in the Aircraft Maintenance Manual and Operations Manual supplements:
- 45 knots up to the door canopy position, 0 (zero) knots beyond the door canopy position, for configuration pre SB PC-757-52-0018 (aluminum rods).
- 45 knots up to the door canopy position, 25 knots beyond the door canopy position, for configuration post SB PC-757-52-0018 (steel rods).
These design changes and wind/gust limitations were mandated by the FAA AD 2016-04-24, which has been adopted by EASA.
FAA mandate of design change to cargo door due to maximum wind operation loading

The Icelandic Transportation Safety Board (ITSB) recommends to the FAA that it requires the STC holder of FAA STC #ST01529SE to review the structural design of the main cargo door with respect to the 45 knots maximum wind operation loading and make the necessary design changes in order to meet the requirements of FAA FAR subchapters 25.301(a) and 25.303.
Afgreiðsla
FAA Safety Recommendation 14.055 was assigned to the FAA's Aircraft Certification Service, Transport Airplane Directorate on April 15, 2014, requiring Precision Conversions to modify the structural design of the main cargo door to support the intended 45 knots maximum wind operation limit in compliance with FAA FAR and EASA CS, subchapters 25.301(a) and 25.303.

Design change to spoiler actuator
Tillaga í öryggisátt
The Icelandic Transportation Safety Board (ITSB) recommends to Moog, in co-operation with the airplane’s manufacturer, set up a program to support fleet wide replacement of the blocking and thermal relief valve housing with the fatigue improved unit made from stainless steel.
Afgreiðsla
Moog has redesigned the Blocking and Thermal Relief Valve Housing with thicker material section and more radius in the area of the fracture surface. The redesigned Blocking and Thermal Relief Valve Housing is made from stainless steel instead of aluminum. This results in better fatigue performance of the Blocking and Thermal Relief Valve Housing. In addition the FAA has issued Safety Recommendation 15.115, a Boeing 757 airplane level safety issue, mandating evaluation of the spoiler actuator's blocking and thermal relief valve housing failure to determine appropriate corrective action.
