Lyfter man med nära maxlast (vilket 9 personer verkar vara) varje gång och gör flera starter om dan så sliter det säkert en del på materialet. En lite extra tvär/brant manöver kan göra att grejorna till slut inte håller.
Jfr hur den finska olyckan gick till (där överlevde piloten).
"The eighth Comp Air flight of the day reached the jump run, which was at 4 230 m over the southern runway of the aerodrome. The skydivers noticed that they had overshot the jump run and requested a new one from the pilot. The pilot increased engine power and simultaneously began turning to the left. During the turn the aircraft began to descend and its airspeed increased, which the pilot did not imme- diately realise. The pilot pulled on the control stick and the aircraft levelled out or went into a shallow climb. He reduced engine power to idle, in conjunction with which the airflow over the horizontal stabi- liser probably decreased suddenly, which generated a rapid nose-down movement. As the angle of attack was decreasing a downward force was generated on the wing. The right wing’s wing strut buck- led upwards and the right wing folded down against the jump door around the wing root mountings. The aircraft lost its controllability instantaneously and began to rotate around its vertical axis in a flight condition resembling an inverted spin."

Det där tycker jag låter som ett rimligt händelseförlopp. Det är också så att den här typen av taxiverksamhet upp och ner kanske gör att man chansar lite mer efter ett par gånger när man kör samma runda och blir varm i kläderna. Samtidigt som man är lite pressad av hopparna som vill ha moment i sin hoppning.
