Part 107 UAS pilot reported flying in controlled airspace and within an active TFR without authorization.

Narrative

During a commercial UAS mission as a wedding videographer capturing video for a high-profile client's wedding day; I was involved in an inadvertent deviation from 14 CFR Part 107 regulations. This resulted in unauthorized entry into Class C airspace and two active Temporary Flight Restrictions (TFRs); an altitude excursion up to 1;407 feet AGL; and operation beyond visual line of sight (VLOS). This event was a direct result of task saturation; accumulated stress and fatigue; and a total breakdown in situational awareness following a last-minute change in mission location.The day prior to the event; the client moved the 'getting ready' location where I was to start filming at a residence in Location X. This new location was within the area of the ZZZ Class C airspace and encompassed by two active TFRs.On the day of the event; I was experiencing significant fatigue from my primary 9-5 job and family obligations - parental responsibilities relating to my children - as well as the stress that comes with filming a wedding day. Upon arrival; I perceived the immediate surroundings and house/filming location as unsuitable for the high-production-value shots required for this celebrity client. Driven by the last minute plan change; pressure to deliver and stress of a 10-12 hour wedding day; I developed 'tunnel vision' and inadvertently bypassed pre-flight planning and a safety checklist.I launched my DJI Mini 4 Pro and given the house was not suitable for filming; focused entirely on trying to get surrounding shots and the camera composition. I inadvertently climbed to 1;407 feet AGL at the highest point to scout for better angles; flying in restricted airspace and beyond VLOS. I was focused on the controller screens image/video shot composition rather than the aircraft's details and position in the airspace. The deviation was identified when a law enforcement officer approached me as I was beginning to bring my drone back for landing. I immediately complied and landed the aircraft safely. No damage whatsoever nor 'close-calls' with manned aircraft or anything occurred.Human Performance & Contributing Factors:Task Saturation & Pressure: The high-stakes nature of the client created significant internal pressure; which resulted in unintentional task-saturation. This caused me to inadvertently focus on cinematography to the exclusion of active airspace monitoring and regulatory compliance.Stress & Fatigue: Accumulated fatigue along with the stress of a wedding day negatively impacted my decision-making and judgment.Loss of Situational Awareness: Due to the last minute change in mission location and pressures of event timeline; I failed to verify the airspace; resulting in a total loss of situational awareness regarding the active TFRs and Class C airspace.Administrative Oversight (Currency Lapse): I identified a lapse in my Part 107 regulatory currency. This was an inadvertent error caused by a misunderstanding of the transition from the previous in-person testing requirements to the current online FAASTeam renewal system and my lack of a formal digital tracking system for my credentials contributing to this oversight.Corrective Actions To prevent a recurrence; I have initiated a comprehensive Safety Improvement Plan:Immediate Compliance: I have confirmed the registration of the UAS involved and affixed the registration number to the aircraft as of Day 0. Having identified the currency lapse mentioned above; I have successfully completed the FAASTeam ALC-677 course to officially restore my regulatory currency and recency of knowledge as of Day 0.Procedural Safeguards: I have created a digital flight log and developed a physical pre-flight safety checklist and inserted it directly on top of my drone in my UAS transport case as a mandatory 'gate' before flight.Technical Safeguards: I have implemented a 'Hard Ceiling' protocol in my flight software for my maximum altitude by setting the UAS maximum altitude limit to a baselineof 65 feet prior to every mission; which is the lowest my UAS software allows me to set it; creating a mandatory technical 'gate.' This requires me to perform a conscious manual override and input the specific airspace ceiling for each new location before the UAS can climb; effectively preventing inadvertent altitude or airspace excursions.Continuing Education: Within days of my incident; I completed the below exams and courses:ALC-677 Part 107 Small UAS Recurrent TestALC-723 10 Decision-Making Concepts for UAS PilotsALC-42 Airspace; Special Use Airspace And TfrsALC-678 sUAS Safety & Risk MitigationALC-803 sUAS Regulations; Laws; Airspace Ownership and FAA EnforcementResource Management: Going forward; I will evaluate mission complexity during the pre-flight phase and utilize a Visual Observer for any operations involving high-density areas or high-pressure environments.
