Anthony E. Grimaldi, Washington, D. C., with whom Charles E. Chisholm, Washington, D. C., was on the brief, for appellant.

Before HOOD, Chief Judge, MYERS, Associate Judge, and QUINN (Associate Judge, Retired).
HOOD, Chief Judge:
Appellant, a student pilot, bought a used Cessna airplane and in order to finance the purchase sought the assistance of one Hammerly, an aviation insurance broker. Hammerly arranged for a loan of $6,115.80, secured by a chattel mortgage on the airplane, from Mercantile National Bank at Dallas. At the same time Hammerly arranged for a $6,000 all risks  ground and flight  aircraft hull policy of insurance by United States Aviation Underwriters, Incorporated. The policy included a "Breach of Warranty" clause which, in general, recognized Mercantile National Bank's lien to the extent of $5,000 even though by some act of appellant the insurer would not be liable to appellant. The policy limited its coverage to flight by appellant while being instructed under the direct supervision of a qualified pilot, or by appellant while holding a pilot's certificate, or by "pilots holding a valid and effective Private or Commercial Pilot Certificate with proper ratings as required by the Federal Aviation Agency for the flight involved, each of whom shall have logged a minimum of 200 hours as Pilot In Command."
The life of the policy was one year and within the year the airplane, while piloted by one McBride, with appellant's permission, was severely damaged in making a landing. Appellant made claim under his *915 insurance policy, the insurer denied liability, and this action was brought.[1]
McBride, at the time of the accident, had less than 60 hours of flight time as pilot in command  far less than the 200 hours specified in the policy  and appellant apparently concedes, as we think he must, that under the terms of the policy the insurer was not liable to pay for the damage. With respect to the insurer's liability to pay the lien holder, it appears that some months after issuance of the policy, the appellant had obtained a loan from a Virginia bank and had paid in full his indebtedness to the Mercantile National Bank at Dallas. Consequently Mercantile had no lien and no claim under the policy. Again, appellant apparently concedes, and again we think he must so concede, that there was no liability on the part of the insurer to pay under the breach of warranty clause because the named lien holder, Mercantile, was no longer a lien holder.
Appellant's contention appears to be that Hammerly, as agent of the insurer, made certain misrepresentations in that (1) he did not tell appellant that the policy excluded coverage when the plane was flown by a licensed pilot with less than 200 hours flying time, and (2) that he did not tell appellant that the breach of warranty clause was applicable only to the named lien holder, the Mercantile National Bank. On the issue of misrepresentation the trial court, sitting without a jury, found that appellant had failed to carry his burden of proof. Hammerly testified that he discussed the insurance with appellant and explained the coverages, specifically telling appellant that it was permissible for a "200-hour pilot" to fly the plane. Thus the issue of misrepresentation, or failure to disclose, presented a question of fact for the trial court, and its finding must stand.
Appellant lays some stress on the fact Hammerly admitted he did not tell appellant that "if he changed the lien holder in the policy that the policy would be void." Had Hammerly made such a statement to appellant, it would have been false. A change of lien holder would not void the primary protection afforded appellant under the policy. Appellant lost his protection not because of a change of lien holder but because he permitted the plane to be operated by a pilot with less than 200 hours flying time.
In connection with the above it may be noted that the breach of warranty clause was for the protection alone of the lien holder in the event appellant because of his own act lost his protection. Under that clause, had the insurer been required to make any payment to the lien holder, the insurer would have been subrogated to the rights of the lien holder and the ultimate loss would have fallen on appellant.[2]
Another of appellant's claims needs little attention. He says his loan from Mercantile National Bank was usurious. This claim was not advanced at trial, the bank was not a party to this action and the insurer was not a party to the loan.
Affirmed.
