flaps extended. Cessna addressed one part of this problem early on, after a flight-test aircraft was damaged when the pilot extended the flaps while taxiing, and his passenger had the clamshell door open (for ventilation; it was a hot summer day). A switch was added to the flap actuation circuit which disabled the flaps when the doors were open. The other part of the problem is that if the flaps are already down, the passenger must perform the complicated procedure of opening the front part as far as possible (about ) then open the rear door and release the spring-loaded rear door handle so it retracts out of the way. This then gives enough clearance to open the rear part of the door fully for egress. Both the 206H and the T206H remain in production in 2013. By the end of 2004, Cessna had produced 221 206Hs and 505 T206Hs, for a total production of 726 "H" models. Cessna has indicated that they do not intend to produce a P206-configuration aircraft in the future, due to lack of market demand. Cessna 207 The Model 207 was a seven- and later eight-seat development of the 206, achieved by stretching the design further by to allow space for more seats. The nose section was extended by adding a constant-section nose baggage compartment between the passenger compartment and the engine firewall; the aft section was extended by by inserting a constant-area section in the fuselage area just aft of the aft wing attach point. Thus the propeller's ground clearance was unaffected by the change (the nosewheel had moved forward the same distance as the propeller), but the tail moved aft relative to the mainwheel position, which made landing (without striking the tailskid on the runway) a greater challenge. The move gave that airplane a larger turning radius, since the distance between mainwheels and nosewheel increased by but the nosewheel's maximum allowed deflection was not increased. The 207 was introduced as a 1969 model featuring a Continental IO-520-F engine of . A turbocharged version was equipped with a TSIO-520-G of the same output. At the beginning of production the model was called a Cessna 207 "Skywagon", but in 1977 the name was changed to "Stationair 7". 1977 also saw a change of engine on the turbocharged version to a Continental TSIO-520-M producing – the same engine used in the TU206 of the same vintage.
