NTSB narrative
The operator of the unmanned aircraft system (UAS) reported that during a test flight, N213PA was intentionally faulted by the UAS operator to simulate a “motor out recovery” and diverted to an alternate landing pad as the system was designed to do. The same fault was applied to N282PA as it was departing, which then diverted the UAS to the same alternate landing pad and into the flight path of N213PA, resulting in a mid-air collision. Both UAS sustained substantial damage throughout.
The operator reported that there were no preaccident mechanical failures or malfunctions with either UAS that would have precluded normal operation.
Probable cause
The operator’s failure to maintain separation between two drones during dual simulated engine out recoveries, which resulted in a midair collision.

Source notes (5)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: 4da17f07df6c397c046e149139f2a6c97a9915b8ab52b9eb674bf18c93af37be; retrieved 2026-09-13T18:46:12.954Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: damage. Narrative states both UAS sustained substantial damage in the midair collision, matching the second aircraft's recorded value.
