EASA releases Annual Safety Review 2018

The European Aviation Safety Agency (EASA) released the Annual Safety Review 2018.

Audit: FAA faces challenges in implementing runway incursion mitigation initiatives

The Office of Inspector General (OIG) of the U.S. Department of Transportation published the findings of their audit into the Federal Aviation Administration’s (FAA) runway safety efforts. 

Due to the increase in runway incursions, in June 2015 FAA initiated a Call to Action forum that focused on developing short-, mid-, and long-term initiatives to mitigate runway incursions and improve safety. In November 2015, FAA published 22 initiatives developed at the forum.
In December 2016 the OIG initiated an audit with the objective to evaluate FAA’s progress in implementing these initiatives.

OIG found that as of November 2017, FAA had completed 10 of the 22 initiatives, including initiatives aimed at educating pilots on signs, markings, and other visual aids at high-risk airports and updating a best practices list for airport surface and movement areas. Ten initiatives are still in progress while two initiatives were canceled. However, the Agency faces challenges in fully implementing the initiatives still in progress. These include dedicating funding to complete four initiatives and fully implementing new technologies for seven initiatives, which could take years to complete. In addition, while FAA has implemented a monitoring plan to track the status of the initiatives, the plan does not tie the initiatives to quantifiable goals or other metrics that would measure their effectiveness in reducing runway incursions.

OIG made three recommendations to the Federal Aviation Administrator regarding revisions to the 2015 Call to Action monitoring plan. FAA concurred with all three recommendations:

  1. Update the target delivery dates for initiatives that are still in progress, including those without target delivery dates, and implement procedures for continually updating delivery dates and descriptions of initiatives as changes are made.
  2. Develop and include in the monitoring plan quantifiable metrics or other indicators that can measure the effectiveness of the initiatives.
  3. Consolidate duplicate initiatives within the monitoring plan.


ANSV Italy reports 46 drone incidents over 2017

The Italian accident investigation board ANSV published it’s Annual Report over 2017, drawing attention to 46 drone incidents over the past year in Italy.

ANSV notes that it continued to monitor interferences recorded in the Italian airspace between unmanned aircraft and manned aircraft. The number of incidents (46) is in line with that of the previous year (51).
Of the 46 incidents reported last year, 42 were conflicts with manned aircraft. Four incidents pertained to single drone operations, for example a bird strike to a tethered drone, and drones observed near airports by ground personnel.
The examination of the airprox reports received by ANSV also shows that a common factor is non-compliance with the national legislation in force. Drones are often operated in areas that are prohibited, e.g. close to airports.

Dutch Safety Board initiates investigation into flying over conflict zones

The Dutch Safety Board will conduct an investigation to assess the follow-up of its recommendations regarding flying over conflict zones, published in the final report of the MH17 crash.

The Dutch Safety Board wants to determine the measures that parties have taken regarding airspace management in conflict zones and in sharing information about threats. The Board also will investigate how operators take into account overflying conflict zones in their risk analyses and in how they give account of the chosen routes.

In accordance with the legal requirements, the Dutch Safety Board examines what parties have done with the results of the investigation and its recommendations.

U.K. AAIB releases Annual Safety Review 2017

The U.K. Air Accidents Investigation Branch (AAIB) released its Annual Safety Review 2017.

The AAIB reported that it received 708 occurrence notifications in 2017 and deployed 38 times to conduct field investigations, 16 of which were fatal accidents in the UK resulting in 28 deaths. A further 204 investigations were conducted by correspondence. Most of the fatal accidents involved General Aviation with the dominant causal factors being loss of control in flight and weather-related issues.

A review of General Aviation accident reports published by the AAIB between 2010 and 2015, inclusive showed similar causal factors. The predominant causal factor was loss of control in flight, which accounted for almost half of the 72 accidents. Of these, most involved the aircraft entering an inadvertent stall and/or spin following engine failure, or during aerobatics.

In 2017 the AAIB issued 29 Safety Recommendations from 8 investigations. As of the end of February 2018, responses have been received for 21 of these 29 recommendations. In assessing the responses, 15 were adequate and closed, 5 were partially adequate and 1 was not adequate.

ATSB released Aviation Occurrence Statistics 2007-2016

The Australian Transport Safety Bureau (ATSB) released the annual Aviation Occurrence Statistics 2007 to 2016.

In 2016, nearly 230 aircraft were involved in accidents in Australia, with another 291 aircraft involved in a serious incident. There were 21 fatalities in the aviation sector in 2016, which was fewer than any previous year recorded by the ATSB. There were no fatalities in either high or low capacity regular public transport (RPT) operations, which has been the case since 1975 and 2010 respectively.

Commercial air transport operations experienced one fatality from 15 accidents; general aviation experienced 10 fatalities from 119 accidents; and recreational aviation had 10 fatalities from 63 accidents.

Collision with terrain was the most common accident or serious incident for general aviation aircraft, recreational aviation and remotely piloted aircraft in 2016. Aircraft control was the most common cause of an accident or serious incident for air transport operators.

Wildlife strikes, including birdstrikes, were again the most common types of incident involving air transport and general aviation operations, with runway events the most common type of incident for recreational aviation.

The accident and fatal accident rates for general and recreational aviation reflect the higher‑risk operational activity when compared to air transport operations. They also reflect the significant growth in recreational aviation activity over the last ten years and this sector’s increased reporting culture.

General aviation accounts for one‑third of the total hours flown by Australian-registered aircraft and over half of all aircraft movements across Australia.

The total accident rate, per hours flown, indicates general aviation operations are 10 times more likely to have an accident than commercial operations, with recreational aircraft around twice as likely to experience an accident than general aviation.

The fatal accident rate, per hours flown, indicates general aviation operations are around 20 times more likely to experience a fatal accident than commercial air transport, and recreational operations are almost 40 times more likely to experience a fatal accident than air transport.

ASN data show 2017 was safest year in aviation history

The Aviation Safety Network today released the 2017 airliner accident statistics showing an extremely low total of 10 fatal airliner accidents, resulting in 44 fatalities. 

The year 2017 turned out to be the safest year ever for commercial aviation, Aviation Safety Network data show.

Over the year 2017 the Aviation Safety Network recorded a total of 10 fatal airliner accidents [1], resulting in 44 occupant fatalities and 35 persons on the ground. This makes 2017 the safest year ever, both by the number of fatal accidents as well as in terms of fatalities. In 2016 ASN recorded 16 accidents and 303 lives lost.

Five accidents involved cargo flights, five were passenger flights. Given the expected worldwide air traffic of about 36,800,000 flights, the accident rate is one fatal passenger flight accident per 7,360,000 flights.

The low number of accidents comes as no surprise, according to ASN President Harro Ranter: “Since 1997 the average number of airliner accidents has shown a steady and persistent decline, for a great deal thanks to the continuing safety-driven efforts by international aviation organisations such as ICAO, IATA, Flight Safety Foundation and the aviation industry.”

On December 31, aviation had a record period of 398 days with no passenger jet airliner accidents. Additionally, a record period of 792 days passed since the previous civil aircraft accident claiming over 100 lives [2].

One out of 10 accident airplanes was operated by an airline on the E.U. “blacklist”.

[1] Statistics are based on all worldwide fatal commercial aircraft accidents (passenger and cargo flights) involving civil aircraft of which the basic model has been certified for carrying 14 or more passengers. Consequently, the June 7 accident involving a Myanmar Air Force Y-8F transport plane that killed 122 is not included.
When including military transport aircraft as well as non-commercial flights, the total number fatalities would be 230 in 24 fatal accidents. Still the lowest numbers in modern aviation history.

[2] Last fatal passenger jet airliner accident: 28 Nov. 2016, Avro RJ85 LaMia, near Medellin, Colombia
Last civil aircraft accident claiming over 100 lives: 31 Oct. 2015, Airbus A321 Metrojet, North Sinai, Egypt (224 fatalities)

The Aviation Safety Network is an independent organisation located in the Netherlands. Founded in 1996. It has the aim to provide everyone with a (professional) interest in aviation with up-to-date, complete and reliable authoritative information on airliner accidents and safety issues. ASN is an exclusive service of the Flight Safety Foundation (FSF). The figures have been compiled using the airliner accident database of the Aviation Safety Network, the Internet leader in aviation safety information. The Aviation Safety Network uses information from authoritative and official sources.

Chinese authorities test drone-aircraft collision

CAAC drone collision test

On November 30, the Civil Aviation Administration of China (CAAC) conducted the first test of a collision between a UAV (drone) and a passenger plane at the Xiangbei Experimental Base of Aviation Industry. This was done to determine the effects of a quad-copter drone hitting the front windshield of a passenger plane in flight.

For the test, an aircraft nose section was manufactured. The mock-up was not based on an actual aircraft model but similar to a domestic jetliner. Two DJI quad-copter drones were then positioned to hit the windshield. One test involved hitting the corner of a windshield, the other dead-center. The speed of the aircraft was described as ‘typical’.

Both outer cockpit window panes cracked as a result of the collision, photos show.

Researchers release report on drone airborne collisions

A research team from the Alliance for System Safety of UAS through Research Excellence (ASSURE) released a report that concludes that drones that collide with large manned aircraft can cause more structural damage than birds of the same weight for a given impact speed.

ASSURE conducted its research with two different types of drones on two types of aircraft through computer modeling and physical validation testing.
Unlike the soft mass and tissue of birds, most drones are made of more rigid materials. The testing showed that the stiffest components of the drone – such as the motor, battery and payload – can cause the most damage. Concentrating those masses on the drone can also cause greater damage, the researchers found.
The research team evaluated the potential impacts of a 2.7-lb. quadcopter and 4 lb. quadcopter; and a 4-lb. and 8-lb. fixed wing drone on a single-aisle commercial transport jet and a business jet. They examined impacts to the wing leading edge, the windshield, and the vertical and horizontal stabilizers. The windshields generally sustained the least damage and the horizontal stabilizers suffered the most serious damage.
The structural damage severity levels ranged from no damage to failure of the primary structure and penetration of the drone into the airframe. However, the research specifically did not explore the risk to flight imposed by that damage. The researchers concluded that unmanned aircraft system manufacturers should adopt “detect and avoid” or “geo-fencing” capabilities to reduce the probability of collisions with other aircraft.
The team conducted a preliminary computer simulation to evaluate the potential damage to engine components if a drone is ingested into an aircraft engine, including damage to fan blades, the nacelle and the nosecone. They plan future additional research on engine ingestion in collaboration with engine manufacturers, as well as additional airborne collision studies with helicopters and general aviation aircraft.
In 2014 Congress directed the FAA to establish a UAS Center of Excellence. The FAA selected ASSURE, led by Mississippi State University, in May 2015.
