ASRS Report: Altitude Deviation

The following report was filed to NASA ASRS in December, 2017, after an instructor and their student experienced a near mid-air collision (NMAC) under IFR...

Traffic Advisory Leads To Traffic Conflict

What started as a normal traffic advisory by ATC, led to this near miss because the student and instructor focused all of their attention on spotting the aircraft above them. It's relatively normal to have traffic just 1,000 feet above you under IFR, so it's likely the crew over-emphasized the traffic risk.

Ironically, the sustained focus on the traffic above them nearly led to an accident. This near miss could have been avoided through a better scanning technique, and dividing attention between multiple tasks. It's easy to get caught staring outside for traffic, when you should be equally focused on flying the airplane.

Had the instructor and student simply leveled off at their assigned altitude, there wouldn't have been a traffic conflict.
