Power Loss on Short Final — Fuel Selector Reality
A fuel-injected trainer, a single tank, and the discipline required to verify fuel state before every flight
The scenario
Departing St. Petersburg Clearwater International Airport (KPIE), Pinellas Park, FL — Runway 18, a 9,730 ft concrete runway. Elevation 11 ft MSL. You are a Private pilot with roughly 180 hours total, current and proficient. This is a local VFR flight in a Diamond DA20-C1, a fuel-injected, fixed-gear, fixed-pitch trainer with a single fuel tank and an ON/OFF fuel selector.
The weather is benign: clear skies, light winds from the east, visibility 10 SM, OAT 24°C. This is a routine local flight — a 45-minute round trip to a nearby field and back. You filed no flight plan. The tower is open (it is 1000 local, within 0600–2300 operating hours). Class D airspace, ceiling 1,600 ft MSL.
You completed a preflight this morning. The fuel tank appeared full — you did not measure it with a dip stick, but it looked full in the sight glass. You did not verify the fuel selector position before engine start (it was in the ON position, where it should be). You did not cross-check fuel quantity with a second method. You did not calculate fuel burn or plan reserves. You simply assumed: full tank, short flight, no problem.
You are now on short final to Runway 18, 2 miles out, 800 ft AGL, descending at 55 KIAS (Vref, approach speed). The engine is running smoothly. The tower has cleared you to land. Everything feels normal.
Aircraft: Diamond DA20-C1, solo, fuel selector ON. Continental IO-240-B, fuel-injected (no carburetor, no carb heat). Single fuel tank with ON/OFF selector — no left/right tank management. Fixed gear, fixed-pitch prop, steam panel. Best glide 73 KIAS.
Pilot: you — Private, 180 hours, current. You did not verify fuel state with a dip stick before flight. You did not calculate fuel burn or plan reserves. You are on short final, committed to landing.

The decision
Before we get into the decision tree — what do you know about fuel management in the DA20-C1? (Pick all that apply; this records your baseline.)
What the record shows
What the NTSB files show
NTSB ERA12FA002 (2011, FATAL): A Temco GC-1B Swift experienced total loss of engine power over the Chesapeake Bay and ditched in the water. The accident resulted from fuel starvation caused by the pilot's failure to verify the fuel selector position before flight or after the power loss. The pilot did not confirm fuel quantity with a dip stick or visual check. The aircraft sank; the pilot did not survive.
NTSB ANC17LA043 (2017): A Cessna T207 on a Part 135 scheduled commuter flight lost all engine power during approach due to fuel starvation. The aircraft made a controlled ditching near Coghlan Island. Contributing factors included unreliable fuel quantity indicators and a company history of fuel management issues. The pilot and passengers survived the ditching.
NTSB LAX97LA278 (1997): A Cessna 150G on a banner towing operation lost engine power and ditched in the Pacific Ocean off California. The accident resulted from fuel starvation caused by the pilot's failure to switch to the auxiliary tank as required by operating procedures. The pilot survived the ditching.
NTSB LAX98LA168 (1998): A Cessna T210M ditched in the Pacific Ocean 2 miles south of Santa Barbara after engine failure on final approach. The accident resulted from the pilot's mismanagement of fuel through improper fuel tank selector positioning. The pilot survived.
The DA20-C1 differs from these accident aircraft in one critical way: it has a SINGLE fuel tank with an ON/OFF selector, not multiple tanks. There is no 'switching to the auxiliary tank' or 'left/right selector' error. The only fuel risk is QUANTITY — running the tank dry through poor planning, or failing to verify fuel state before flight. The fuel selector position is binary: ON or OFF. If it is OFF, the engine will not run. If it is ON and the tank is empty, the engine will not run.
The real accidents cited above occurred at other airports and in other aircraft — NOT at KPIE. But the teaching angle is identical: fuel management discipline means dip stick checks, fuel burn calculation, reserve planning, and verification of fuel state before every flight. Relying on 'it looked full' or memory from the previous flight is the path to fuel starvation.
At KPIE, the off-field environment matters: off Runway 18's departure end (heading 171°), the terrain is medium development and open developed areas — rough for a forced landing, but survivable. Off Runway 36's departure end (heading 351°), the terrain is open water — a ditching. If you depart Runway 04 or 22, the off-field environments are water (Runway 04) or dense development (Runway 22). Know the off-field reality before you line up.
Key lesson — The DA20-C1 has a single fuel tank and an ON/OFF selector. Fuel starvation is a quantity problem, not a selector-position problem — but only if you verify fuel quantity before flight with a dip stick. 'It looked full' is not a fuel check. Calculate fuel burn, plan reserves, and cross-check fuel quantity with a second method. On short final, an engine failure is a dead-stick landing — establish best glide (73 KIAS) immediately and commit to the runway if it is reachable. At KPIE, Runway 18 is reachable from 800 ft AGL on short final; off-field landing should be a last resort, not a first choice.
Debrief — teaching points
Fuel management in the DA20-C1 is a quantity problem, not a selector-position problem.
The DA20-C1 has a single fuel tank with an ON/OFF selector. There is no left/right tank switching, no auxiliary tank, no 'both' position. The only fuel risk is running the tank dry through poor planning or failing to verify fuel quantity before flight. A dip stick check is the only reliable way to know how much fuel is actually in the tank. The fuel quantity indicator is mechanical and can be unreliable. 'It looked full' is not a fuel check. Measure it.
Fuel discipline means: dip stick check, fuel burn calculation, reserve planning, and verification before every flight.
Before every flight, not just the first flight of the day: dip stick the tank, calculate fuel burn for the planned flight, plan a reserve (typically 30 minutes for day VFR), and verify the fuel selector is in the ON position. Do not assume the tank is full because it was full yesterday. Do not rely on memory or the fuel quantity indicator. Measure it, calculate it, verify it. This is not optional; it is the foundation of fuel management.
On short final with an engine failure, establish best glide (73 KIAS) immediately and commit to the runway if it is reachable.
At 800 ft AGL on short final to a 9,730 ft runway, an engine failure is a dead-stick landing, not an emergency. Establish 73 KIAS best glide immediately, point toward the runway, and commit. At best glide, you have roughly 6,000 ft of glide distance from 800 ft AGL — more than enough to reach a 9,730 ft runway. Turning away from the runway to look for an alternate landing area costs altitude and distance and is the wrong decision. Commit to the runway.
The fuel-injected Continental IO-240-B has no carburetor heat or carb ice risk, but fuel starvation is still possible.
The DA20-C1's Continental IO-240-B is fuel-injected, not carbureted. There is no carburetor heat, no carb ice, no carb-ice troubleshooting. But fuel starvation is still the most likely cause of an engine failure at low altitude. If the engine quits on short final, verify the fuel selector is ON and the tank has fuel. If the selector is ON and the tank is empty, the engine will not restart — you have a dead-stick landing.
Off-field environment at KPIE: Runway 18 departure is medium development (survivable); Runway 36 departure is open water (ditching).
Know the off-field reality before you depart. Off Runway 18's departure end (heading 171°), the terrain is medium development and open developed areas — rough for a forced landing, but survivable. Off Runway 36's departure end (heading 351°), the terrain is open water — a ditching. Off Runway 04 (heading 40°), the terrain is open water. Off Runway 22 (heading 220°), the terrain is dense development. If you lose the engine on departure, know where you can land safely.
