DEHAVILLAND DHC-3 · Model Guide
Overview
DEHAVILLAND DHC-3 is the de Havilland Canada Otter, listed as a single-engine piston aircraft. Registry data for the DHC-3 family shows up to 12 passengers, up to 3600 kg MTOW, up to 124 kt cruise, up to 900 nm range and a 20500 ft ceiling. The documents supplied cover turbine-conversion service bulletins and a STOL kit, so check which modifications a given airframe carries.
- Family-level maxima: 12 passengers, 900 nm range, 124 kt cruise, 20500 ft ceiling. These are not figures for any one airframe.
- Many Otters carry aftermarket changes: Texas Turbine conversions and the Baron STOL kit. Confirm the STCs and flight manual supplements on the aircraft.
- Early Texas Turbine conversions had a fuel check-valve problem. Confirm that SB-DHC3-01 was done.
- The optional parallel/series start system cuts start time and start temperature, but it adds weight.

Which service bulletin should I check on a turbine-converted DEHAVILLAND DHC-3?
For a DEHAVILLAND DHC-3 with a Texas Turbine conversion made before October 1, 2002, check compliance with SB-DHC3-01. It fixes fuel check valves that could block feeding from the aft tanks.
Can a DEHAVILLAND DHC-3 with the Baron STOL kit use floats or skis?
Yes. The supplement says the kit is compatible with any approved wheel or ski installation and with approved floats. It is also compatible with any approved piston or turbine engine installation.
Is the faster start system mandatory on the DEHAVILLAND DHC-3?
No. For Texas Turbine-converted DEHAVILLAND DHC-3 aircraft, the parallel/series start system in TTC-SB-DHC3-03-REV-A is optional. It adds 5.3 pounds and takes up to 16 man-hours to install.

Fuel system check (turbine conversions)
Service Bulletin SB-DHC3-01 (April 25, 2003) covers Texas Turbine conversions made before October 1, 2002. Faulty check valves could stop fuel feeding from the aft tanks. The fix was due within 100 hours or at the next 100-hour inspection, and it returns the fuel system to the original DeHavilland layout. Ask for proof of compliance.
Baron STOL kit supplement
The Stolairus Baron STOL kit supplement (revision 3, 05/22/2015) is compatible with any approved wheel, ski or float installation. It is also compatible with any approved engine installation, piston or turbine. It changes the aft CG limit. The supplement says performance meets or exceeds the basic flight manual. With some floats fitted, avoid intentional side slips with flaps down.
Optional start system upgrade
Service Bulletin TTC-SB-DHC3-03-REV-A (October 1, 2006) is optional. It raises starter voltage from 24V to 48V during the start only. It cuts start time by as much as 20 seconds and start temperature by as much as 100C, which helps water operations. Installation takes up to 16 man-hours. The kit adds 5.3 pounds at station 42.0.
Summary written by AI from the source document. Check the original before relying on it. See which parts of Sprinkle are written by AI.
Safety notes
- Under SB-DHC3-01, do not take off with less than 134 lbs (20 U.S. gal.) of fuel in all three tanks.
- Burn from the front tank for takeoff and landing. After takeoff, burn from the aft tank forward.
- Use the electric boost pump for takeoff, landing, fuel tank selection and operations above 10,000 feet.
