Russia imposes restrictions on international flights of Yakutia Airlines over safety issues

The Russian Federal Air Transport Agency (Rosaviatsiya) has imposed restrictions on international flights of Yakutia Airlines over safety issues.

The reason for the introduction of the restriction was the violations identified during recent inspections, including incorrect information about the implementation of the airworthiness directives on the Boeing 737-800 aircraft and its further operation without maintenance; and failure to eliminate in time the malfunctions identified on the aircraft.

The agency states that the maintenance issues have caused long and numerous delays on international and domestic routes.

From November 5, the company is prohibited from flying on international airlines and will remain in force until the elimination of all identified deficiencies.

The air fleet of Yakutia Airlines consists of 5 Boeing 737-800’s, 6 Antonov An-24RV’s, 3 DHC-8-311’s and 4 Sukhoi Superjets.

TSB Canada releases safety watchlist 2018

The Transportation Safety Board of Canada (TSB) released Watchlist 2018, identifying key issues requiring government and industry’s attention to make Canada’s transportation system safer in the air, marine and rail sectors. 

This year, one aviation item was removed from the Watchlist due to actions taken by stakeholders and/or progress achieved in reducing the underlying safety deficiencies: the issue of unstable approaches that are continued to a landing at Canadian airports.

Still on the list are the following aviation-related items:

  • Risk of collisions on runways
  • Runway overruns
  • Safety management and oversight  (multimodal)
  • Slow progress addressing TSB recommendations  (multimodal)
  • Fatigue management (multimodal)

EASA extended Conflict Zone Information Bulletin for South Sudan to 26 April 2019

The European Aviation Safety Agency (EASA) updated and extended the validity of its Conflict Zone Information Bulletins for South Sudan to 26 April 2019.

FAA extends and amends flight ban for Ukraine’s Simferopol and Dnipropetrovsk FIRs

The U.S. Federal Aviation Administration (FAA) extended the prohibition on flight operations in the Simferopol (UKFV) and Dnipropetrovsk (UKDV) FIRs in Ukraine, but reduced the area of impacted airspace.

The FAA initially banned all U.S. flights from the Simferopol and Dnipropetrovsk areas on July 18, 2014, the day after Malaysia Airlines flight MH17 was shot down near Hrabove, Ukraine. The FAA continued to evaluate the situation in the area and in 2016 determined there was a continuing significant flight safety hazard to U.S. civil aviation. This lead to an extended flight ban.

Since the 2016 final rule, the FAA assessed that security and safety conditions have sufficiently stabilized in certain regions of Ukraine, thereby reducing the area of impacted airspace in specified areas of the Simferopol FIR (UKFV) and Dnipropetrovsk FIR (UKDV). The FAA thus revised the flight prohibition to allow U.S. civil flights to resume in certain areas. However, the FAA finds an extension of the prohibition is necessary in other specified areas of Ukraine to safeguard against continuing hazards to civil aviation.

EASA extends conflict zone warning for Syrian airspace

Damascus FIR (Syrian airspace)

On October 18, the European Aviation Safety Agency (EASA) extended the validity of Conflict Zone Information Bulletin CZIB 2017-03R3 to 18 April 2019.

The risk is described as:

Due to the hazardous security situation, with the presence of terrorist organisations and ongoing high intensity military operations, there is a risk of both intentional targeting and misidentification of civil aircraft. The presence of a wide range of ground-to-ground and dedicated anti-aviation weaponry poses a HIGH risk to operations at all flight altitudes.

EASA extends conflict zone warning for Iraqi airspace

The Baghdad FIR roughly follows the Iraqi border

On October 15, the European Aviation Safety Agency (EASA) extended the validity of Conflict Zone Information Bulletin CZIB 2017-04R3 to 15 April 2019. The risk is described as:

Due to the presence of various weaponry including MANPADS (man-portable air-defence systems), it is advised to be 
cautious with the risk associated to civil aviation. The risk to operations at all altitudes is assessed to be HIGH, 
except for airways UM688 and UM860. The highest airspace risk is estimated to be along the entire Iraq/Syrian border.

EASA withdraws conflict zone warning for Kenya

The European Aviation Safety Agency (EASA) withdrew its Conflict Zone Information Bulletin (CZIB) for Kenya on 26 September 2018.

The agency first published a conflict zone alert on Kenya on 9 September 2016, referring to U.K. (CAA) and U.S. (FAA) warnings that stated “to exercise caution when flying into, out of, within, or over the territory and airspace of Kenya at altitudes below FL260 due to the possibility of extremist/militant activity.”

The CZIB’s validity was extended several times. The most recent extension was published on September 3, 2018. In that edition, EASA explicitly added a new warning:  “The presence of terrorist groups with the military capabilities (including anti-aircraft weaponry) is assessed to pose a HIGH risk to operations within Kenyan airspace and territory FIRs at altitudes below FL 250.

EASA stated that their reason for the withdrawal of the alert, was that “the latest EU Risk Assessment indicated that airspace security threat has reduced over time […] (the situation has become more stable in this region), namely there is no longer a HIGH risk for Medium or High altitude overflight.”

While EASA withdrew their alert, the CAA and FAA warnings for Kenya were still valid (on September 26).

FAA warns for potential takeoff data errors due to runway number transposition

The U.S. Federal Aviation Administration (FAA) is alerting pilots on the risk of a potential takeoff data error due to runway number transposition.

The FAA reports that in 2017 an airline identified a runway event which saw an aircraft utilize the carrier-provided Takeoff Performance System (TPS) data for runway 10L, while actual departure was off of runway 01L. This resulted in an actual takeoff runway length (for 01L) that was 4,220 feet less than what was calculated by the TPS (for 10L). The data provided for runway 10L offered three flap settings (1, 5, 15) and three thrust settings (22K, 24K, 26K) for takeoff. A setting of Flaps 1 and thrust 22K was selected. This resulted in a rotation at standard speed, and a takeoff with 400 feet of usable takeoff distance remaining.

Although an FAA analysis identified several other U.S. airports with the potential of a transposition error involving runways of significantly different lengths, the majority of the runway transpositions occurred at San Francisco International Airport (SFO).

FAA issues advisory to pilots about risks associated with operating in Iranian airspace

The U.S. Federal Aviation Administration (FAA) issued an advisory, warning pilots about risks associated with operating in Iranian airspace within the Tehran Flight Information Region (FIR).

The FAA states that, due to concerns about deconfliction between military activities and civil flight operations, there is continued risk to U.S. civil aviation operating in the Tehran FIR. For this reason, the FAA published Notice to Airmen (NOTAM) KICZ A0016/18, advising U.S. civil aviation to exercise caution when operating into, out of, within, or over the Tehran FIR (OIIX). The NOTAM also advised U.S. civil operators and airmen operating in or adjacent to the Tehran FIR (OIIX) to carefully review current NOTAMs and other sources of aeronautical information and be familiar with current conditions in the Middle East.

The FAA among others cites military activities emanating from or transiting through the Tehran FIR (OIIX) that are associated with the conflict in Syria. These activities include, but are not limited to, Russian air-launched cruise missile attacks launched from over Iran toward targets in Syria and Russian maritime-launched land-attack cruise missiles fired from the Caspian Sea. There is the potential for Iranian surface-to-surface missile fire from western Iran, targeting Islamic State of Iraq and al-Sham (ISIS) positions located in the region. Iran has also conducted multiple missile test launches in the Tehran FIR (OIIX). These activities present a military-civil deconfliction challenge in the region. Additionally, there is an inadvertent risk to U.S. civil aviation operations in the Tehran FIR (OIIX) from Iranian-fielded GPS jammers.
