I doubt the story. But, there is THIS, which may (or may not—caution!) be relevant:
Iran: US Plane Leaves After Emergency Landing

TEHRAN, Iran December 30, 2012
A small American commercial plane left Iran Sunday after it was repaired following an emergency landing at an Iranian airport this month, state TV reported.
The plane was forced to land 16 days ago at the airport of the southern city of Ahvaz due to technical failure, Mahmoud Rasoulinejad, head of the state-owned Iran Airports Company, told the TV station.
It was not clear why the announcement of the plane’s landing was not made earlier.
