- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Approach
- First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- In flight collision with object
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
- Tree(s)
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
- Destroyed

NTSB narrative
DURING AN IFR ARRIVAL AT NIGHT, THE PILOT WAS CLEARED FOR THE VOR RUNWAY 27 APPROACH TO THE PUTNAM COUNTY AIRPORT. THE PUBLISHED MINIMUM DESCENT ALTITUDE (MDA) FOR THE APPROACH WAS 1200 FEET MSL OR 437 FEET AGL. WITNESSES DESCRIBED THE WEATHER AS 'FOGGY' WITH DRIZZLE AND 1 MILE VISIBILITY. DURING THE APPROACH, THE AIRPLANE STRUCK TREES THAT WERE ABOUT 60 FT TALL AND 1 1/2 MILES EAST-SOUTHEAST OF THE AIRPORT. AN EXAM REVEALED THAT INITIAL IMPACT OCCURRED WITH TREETOPS ON A HEADING OF 315 DEG IN A WINGS ATTITUDE. NO PREIMPACT PART FAILURE WAS FOUND. A MARK ON THE AIRSPEED GAGE INDICATED IT WAS AT THE 140 KT POSITION DURING IMPACT. BOTH PROPELLER BLADES HAD CHORWISE SCRATCH MARKS AND 'S' BENDING AT THE TIPS. THE SURROUNDING TERRAIN AT THE AIRPORT WAS FLAT AND SPARSLEY POPULATED. THE AIRCRAFT WAS BASED AT THE AIRPORT, AND THE PILOT HAD FLOWN IN THE LOCAL AREA FOR SEVERAL YEARS. NO RECORDS WERE FOUND TO DETERMINE THE PILOT'S INSTRUMENT FLIGHT OR NIGHT FLIGHT PROFICIENCY.
Probable cause
FAILURE OF THE PILOT TO FOLLOW THE PROPER INSTRUMENT PROCEDURE AND MAINTAIN THE MINIMUM DESCENT ALTITUDE (MDA) DURING AN APPROACH TO THE AIRPORT AT NIGHT IN INSTRUMENT METEOROLOGICAL CONDITIONS.

Source notes (4)
- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1990-10-08.
