We present the preliminary results of a 40.8 ks Chandra ACIS observation of the young supernova remnant (SNR) N103B located in the Large Magellanic Cloud. The image reveals structure at the arc-second level, including several bright knots and filamentary structures. The remnant has the characteristic spectrum of a type Ia SNR, containing stron lines of Fe, He- and H-like Si, S, Ar, and Ca. Spectra of several bright knots are presented. Preliminary analysis, including equivalent width images in the brighter lines of Si and S have revealed spatial variations in the emission strength of these elements. These variations are further explored.
