MEMORANDUM *

We reverse the judgment in favor of Yellow Freight System, and direct summary judgment in favor of Kvaerner E & C (Metals). Although the statute1 and the regulations2 might be construed otherwise, we are bound by their construction in Culver v. Boat Transit, Inc.3 and Insurance Co. of North America v. G.I. Trucking Co.4

Kvaerner’s February 8, 2000 letter, and the attached itemized list of damage to the pumps, gave Yellow Freight written notice that Kvaerner intended to make a claim. Yellow Freight sent its area representative, Denver Price, to inspect the damage, and Price provided Yellow Freight with his *173January 6 inspection report. Kvaerner’s manager called Price at Yellow Freight within a month of receiving Ingersoll Dresser Pump Company’s March 16, 2000 repair invoice, and advised Price that the claim was “in the neighborhood of’ $70,000 to $75,000. This was a reasonable estimate of the $75,981 in actual damages. Although Yellow Freight asked Kvaerner to report to another department, and that department asked Kvaerner to provide additional extensive detail on Yellow Freight’s forms, which was not done until after the nine-month deadline for making a claim, Kvaerner had already met the nine-month deadline under Culver and G.I. Trucking before those forms were filed.

G.I. Trucking establishes that a reasonable estimate of the damages suffices, even though it is not the exact amount of the claim, and that such “substantial performance” suffices “to permit the carrier to make a prompt and thorough investigation.”5 Although in G.I. Trucking, the estimate was provided in writing, Culver eliminates the materiality of that distinction. Culver holds that “[1] a written notice of damage, coupled with [2] a clearly communicated intent to hold the carrier liable, plus [3] the carrier’s investigation, suffices as a written claim.”6 All three requirements were satisfied by Kvaerner by March 2000. Although the carrier was more involved with the repairs in Culver than here, that distinction does not make a difference to the timeliness of the shipper’s written claim and the carrier’s knowledge of the determinable amount.

REVERSED and REMANDED.
