Notification on the renaming of the Civil Aviation Safety Investigation and Analysis Center

Considering the Government Ordinance no. 17 of 29 August 2018, published in the Official Gazette of Romania, Part I, no. 755 of 31 August 2018, we notify you that the Civil Aviation Safety Investigation and Analysis Authority (CIAS) has been renamed as the CIVIL AVIATION SAFETY INVESTIGATION AND ANALYSIS AUTHORITY (SIAA).

The influence of weather conditions on civil aviation events

February 22, 2013

The Civil Aviation Safety Investigation and Analysis Center (CIAS) representatives attended the Aviation Weather Safety Workshop event, organized by Aircraft Owners and Pilots Association (AOPA) on February 21, 2013.

The event was also attended by the representatives of the Ministry of Transport, Romatsa, as well as many pilots and aircraft owners. During the debate session, Eugen SUCIU, CIAS investigator, sustained a presentation having as theme the influence of weather conditions on civil aviation events.

In 2012, 1150 events were reported to the Civil Aviation Safety Investigation and Analysis Center (CIAS), 239 more than last year. Based on reports received by CIAS, from the total number of 2012’s reported events, weather conditions were a relevant factor in 17 incidents, 1 accident and 1 serious incident. 94% of these events occurred on commercial airlines.

The wind was the main meteorological factor in causing civil aviation events, followed by atmospheric visibility and visibility measurement. According to CIAS investigation reports, a lower share in those accidents causes was attributed to general weather conditions, rainfall, cloud formations and day / night conditions, as you can see from the chart below:

The investigations carried out by CIAS specialists showed that wind shear was the main relevant factor upon the civil aviation events reported in 2012, by having a differential impact depending on flight phase:

CIAS presentation continued with three case studies exposing punctual situations when weather conditions proved to be the main factor of aviation events:

  • the serious incident that occurred near Niculesti (Buzau county), on November 28, 2011 (for more information, about the preliminary report on flight safety investigation,click here raportul preliminar privind investigatia de siguranta a zborului)
  • the major incident during the flight, on LRCV-LRTR route, on February 13, 2012, by a SAAB 2000 aircraft having 48 passengers on board (for more details, preliminary report can be accessed here)
  • the major incident on Iasi Airport, on August 11, 2012 (preliminary report is available here).

The Civil Aviation Safety Investigation and Analysis Center aims to increase civil aviation safety and maintain its high level by making recommendations regarding flight safety, and, based on the information resulted in technical investigations, in order to prevent incidents and / or similar accidents in civil aviation. We are looking forward to receive more accurate notification from all air operators (AOA and AOC) and pilots.

“Our activity is based on values that regard security, trust, responsibility, expertise and professionalism. Having some of the best specialists, we intend to transform the statistics finding that “air travel is the safest mode of transportation”, into a feeling of trust for all civil aviation beneficiaries”, said Nicolae STOICA, General Manager of CIAS.
