I want to analyze aviation safety fleet ageTravel and Tourism

Task prompt

I want to analyze aviation safety, fleet age, and operational reliability for domestic airlines operating in Nepal. Act as an autonomous web agent. Maintain a living working state file (working_dossier.md) and update it after every step. If any aviation database page fails twice, revert to your scratchpad and pick an alternative official report. First, freeze analysis steps and review official European Union Air Safety List (EU Air Ban) records and International Civil Aviation Organization (ICAO) Universal Safety Oversight Audit Programme (USOAP) reports for Nepal. Next, evaluate 5 domestic airlines operating in Nepal (Buddha Air, Yeti Airlines, Shree Airlines, Sita Air, and Tara Air). Inspect aircraft fleet compositions (ATR 72-500, DHC-6 Twin Otter, Bombardier CRJ-200, Dornier 228), average fleet ages, and Civil Aviation Authority of Nepal (CAAN) safety circulars. Finally, calculate safety and reliability scores for each carrier and compile a 25-section aviation analysis report with direct document links.
