Denver Intl — Safety History & Runway Risks
NTSB accident analysis for KDEN: 25 events analyzed
Denver, CO · 5433.8 ft MSL · 6 runways
Based on 25 NTSB events at KDEN (Denver Intl), the most important risks for pilots are:
- Crosswind excursion on takeoff. The most serious multi-injury event in the dataset (Dec 2008, Continental 1404, 6 seriously injured) involved a runway excursion on 34R in a 27-kt wind gusting to 42 kts from 270°, a direct 90° crosswind. The probable cause was loss of directional control when the captain ceased rudder input in a gusty crosswind exceeding his experience level.
- Density altitude and performance degradation. At 5,433 ft MSL, KDEN's true density altitude on a summer afternoon can easily exceed 8,000–9,000 ft. The Sep 2023 event (Boeing 737-9 wheel fire) was directly caused by overheated brakes from extended taxi at higher power settings needed to burn fuel to reach proper takeoff weight — a performance-environment interaction. GA aircraft are far more vulnerable to density altitude effects than the jets in this dataset.
- Tailstrike on landing due to improper flare or incorrect airspeed. Three separate tailstrike events occurred at KDEN: a Boeing 737 in Jun 2019 (early flare, high pitch attitude), an Airbus A320 in May 2009 (excessive pitch-up with a tailwind after a bounced landing), and an MD-11 in Jan 2013 (incorrect landing speeds from a wrong weight entry). All three occurred in VMC or near-VMC, indicating technique and data errors rather than weather as primary causes.

Safety History
25 eventsKDEN has recorded 25 NTSB events from 2008–2025, with no fatalities across all events and a recent decline in activity (4 events in the last 5 years). The dominant safety themes are crosswind/directional control on takeoff, landing gear and brake system failures, tailstrikes on landing, and bird strikes — all compounded by KDEN's high-density-altitude environment at 5,433 ft MSL. GA pilots should pay particular attention to crosswind conditions on north-south runways, density altitude performance planning, and thorough gear-system preflight inspection.
The 17-year record shows a clear concentration of events in 2008–2013 (17 events) with a significant reduction since 2014. Zero fatalities across all 25 events is notable, though 9 serious injuries were recorded across multiple incidents.
- •Landing gear failures are the single most represented failure category, appearing in at least 6 events spanning multiple aircraft types.
- •All three recorded tailstrike events occurred in VMC, pointing to technique and CRM factors rather than low-visibility conditions.
- •The Dec 2008 crosswind excursion (Continental 1404) remains the highest-consequence event by injury count, with 6 serious injuries.
- •Smoke and fire events (engine fire, tailpipe fire, galley overheat) account for 5 separate events across the dataset, none of which resulted in fatalities.
- •Bird strikes have been recorded in both the approach phase and during landing roll, indicating hazard is not confined to a single phase of flight.
- •Ground operation incidents (ramp collision, runway incursion, snowplow strike) account for 3 events, reflecting the complexity of KDEN's ground environment.
