After the 2005 crash, the Federal Aviation Administration grounded the Grumman G-73T Mallard that Chalk’s* flew, because of metal cracks in the wings. In August 2006, Chalk's resumed flights using 19-seat conventional planes leased from Montana-based Big Sky Airlines.
The 2005 crash shook confidence in Chalk's and left it without a fleet of its own. In its Sept. 30, 2007 order, the Department of Transportation said it gave Chalk's more than a year to get the Federal Aviation Administration to re-certify its Mallard seaplanes, or to acquire new planes, but it did neither, so the department revoked its flying charter
