Close Calls & Voluntary Reports

Recreational / Hobbyist UAS pilot reported learning post-flight they conducted two UAS flights in an area where UAS flight is restricted.

SNA Tower controllers reported that a general aviation aircraft overshot the centerline of the parallel runway; creating a conflict with an air carrier aircraft who took evasive action to avoid a possible collision.

Recreational / Hobbyist UAS pilot reported conducting a flight in controlled airspace without authorization. The pilot also reported briefly losing VLOS of the drone.

Part 107 UAS pilot reported inadvertently flying without having met Remote Pilot recurrent training requirements.

Part 107 UAS pilot reported taking off and flying above the maximum altitude for one LAANC grid while transitioning to another LAANC grid.

Air carrier Captain reported a lack of designation of boundary line; and that taxiway lines were barely visible during taxi at ORD.

Air carrier Gate Agent reported that safety lines on the EWR ramp are difficult to see prior to operating the jet bridge.

Part 107 UAS pilot reported conducting a UAS flight under a Certificate of Authorization that only applied to another pilot. The pilot landed the UAS upon realizing this error.

Citation Excel Captain reported that an inflight upset occurred when they encountered wake turbulence on descent into PHX in trail of a commercial jet.

B737 Captain reported a momentary loss of control after encountering wake turbulence on descent into ORD in trail of a B777.

B737 flight crew reported a momentary loss of control when they encountered wake turbulence while being vectored for final approach to LGA.

Government UAS pilot reported possibly flying in controlled airspace without authorization. After checking; they confirmed no airspace violations.

Recreational / Hobbyist UAS pilot reported flying above the LAANC authorized altitude during a flight; causing an airborne conflict with a crewed aircraft. The UAS pilot landed the UAS upon realizing they had flown above the approved altitude.

Part 107 UAS pilot reported they learned during post-flight they flew in controlled airspace without authorization.

General aviation pilot reported taxiing past a charted taxi limit hot spot depicted on the HHR taxi chart; and cited a lack of airport signage as a contributor to the incursion.

Air carrier pilot reported an NMAC with a UAS during final approach. No evasive action was taken.

Air carrier First Officer reported an NMAC with what they thought was a balloon or UAS while descending on arrival.

N90 TRACON Controller reported congestion involving VFR aircraft; arrival aircraft getting RAs from departures; and aircraft skirting the Bravo airspace.

Government UAS pilot reported conducting a UAS flight in controlled airspace without LAANC authorization.

Flight Instructor reported airborne conflicts with two groups of UAS while performing training maneuvers.

Air carrier flight crew reported GSP Approach and Tower closed without notifying the crew during descent.

Fractional Captain reported AXH departure procedures should reflect ODP and instruct to turn to the right and not to the left for obstacle avoidance.

Air carrier Captain reported conflicting altitude crossing information at waypoint ENAGA on the MMMX ENAGA3 STAR between the FMS and Jeppesen chart.

Government UAS pilot reported learning post-flight they flew in controlled airspace without authorization.

General aviation pilot reported the noise abatement sign at PWM airport distracts pilots from the hold-short line.
