Design of pulley fastener locking
Tillaga í öryggisátt
The Icelandic Transportation Safety Board (ITSB) recommends to Technify Motors to reconsider the design of the crankshaft belt pulley fastener P/N 05-7223-K000501 in order to prevent loosening of the fastener.
Afgreiðsla
Technify Motors reconsidered the design of the crankshaft belt pulley fastener P/N 05- 7223-K000501 in order to prevent loosening of the fastener and provided a report to EASA. In the report different options of locking mechanism were considered. The preferred solution was to mark the bolt with torque seal and decided to implement it. This way, the security of the correct sit of the crankshaft main bolt could be checked during inspections, to see if it was loosening over time.
Design change to spoiler actuator

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.
Critical pulley fastener notification
Tillaga í öryggisátt
The Icelandic Transportation Safety Board (ITSB) recommends to Technify Motors to issue a service letter to operators, advising of this incident and remind them never to loosen the belt pulley fastener in the crankshaft, due to its critical torque value.
Afgreiðsla
Technify Motors added several notes to repair procedures (RM-02-02) during which the mechanic might have the idea to demount the pulley and informed all registered users regarding the new versions.

Change to emergency slide system
Tillaga í öryggisátt
In conjunction with the manufacturer, ensure that necessary changes are made to the emergency escape slide design of RRJ-95B aircraft EASA certified under type certificate EASA.IM.A.176 to meet the maximum wind requirements of EASA CS-25.810(iv)
Afgreiðsla
EASA has contacted the manufacturer and the Interstate Aviation Committee-AR in order to review the compliance of the slides with the certification requirements.
Change the classification of the control zones

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.

Bætt eftirfylgni vegna símhringinga í 112
Tillaga í öryggisátt
RNSA beinir því til Neyðarlínunnar að bæta eftirfylgni vegna símhringinga án skýrrar tjáningar þess sem hringir.
Afgreiðsla
Neyðarlínan hefur ekki mótað verklag um bætta eftirfylgni símhringinga sem berast án skýrrar tjáningar þess sem hringir, sbr. tillögu RNSA Neyðarlínan hefur hins vegar ítrekað það verklag sem viðhaft hefur verið í gegnum árin að neyðarverðir hringi til baka, ef símtal slitnar, ef minnsti grunur leiki á því að innhringjandi sé í vanda. Eftirfylgni neyðarsímtala almennt er til skoðunar samhliða rýni og endurskoðunar gæðahandbókar Neyðarlínunnar sem nú er í gangi.
