Operation under visual flight rules requires information about the presence of air traffic, especially in non-controlled public aerodromes. This is essential for pilots to make a comprehensive control of the situation. New Safety Report.

JIAAC published a new Safety Report (see in: https://jiaac.gob.ar/files/55366-16.pdf) that includes recommendations addressed to the National Civil Aviation Administration (ANAC) and the Argentine Federation of Airclubs (FADA).

In Safety Recommendation (SR) 1637, ANAC is requested to “evaluate the integrity and effectiveness of the provisions governing operations in non-controlled public aerodromes to ensure separation between aircraft.”

It asks for “the evaluation of the actual utilization degree in general aviation operations daily practice of the 123.5 communication channel for general calls in the non-controlled aerodromes of the country, especially in those whose volume of flight activity expose them more to the possibility of loss of separation and/or aircraft collisions during their operations.”

ANAC is also requested to adopt measures that guarantee the effective implementation of the use of the VHF general call channel for aerodromes lacking air traffic services and reported fit places used as a support of the “see and avoid” principle.

The report is connected to the in-flight collision of March 8, 2016, between aircraft Cessna 150M, registration LV-CQJ and Petrel 912i LV-BSH in a field adjoining the General Rodriguez aerodrome.

A similar in-flight collision occurred near the Ezpeleta aerodrome in July 2015. This occurrence triggered the creation of a Recommendation addressed to the Airclub that owns the aircraft regarding the incorporation of that aerodrome to the transit circuit. SR 1575 asked “to stop the use of the informally established procedure for incorporation to the transit circuit of the aerodrome and instead, to follow the procedure reflected in MADHEL.”

In this case, the response from the Airclub was positive as it adopted provisions to adjust the operations “to the statements in Annex Bravo, except point c) in which the value will be replaced by 650 ft in accordance with the release of permanent NOTAM C1734/2016.” In an agreement signed by the Airclub authorities and the Chief Aerodrome Officer, it was also declared that it will be done “in accordance with RAAC 91 (…) for each particular circumstance.” JIAAC considered this response as appropriate and changed its status to ‘closed’.

GEZ Aerodrome

In the case of this report, SR 1639 was also issued requesting ANAC to initiate a safety risk evaluation for Durana Aerodrome in General Rodriguez (province of Buenos Aires), with the aim of generating the necessary information to turn this air terminal into a controlled aerodrome.

Finally, the report includes SR 1638 addressed to FADA for the dissemination of this accident documentation to its member associations, in order to warn pilots of the particular conditions of this aerodrome.
